I am trying to print a warning message that is a little long and includes 2 variable calls. Here's my code:
warning( 'MATLAB:questionable_argument', ...
'the arguments dt (%d) and h (%d) are sub-optimal. Consider increasing nt or decreasing nx.', ...
dt, h )
Obviously, the line of text extends to the right when viewing the MATLAB code. How can I break it so it wraps nicely? I've tried multiple things but keep getting syntax errors.
As suggested in comments, just insert a \n where you want to break the line. You can also use a variable for the text, to make it easy to read also within the code:
txt = sprintf(['the arguments dt (%d) and h (%d) are sub-optimal.\n'...
'Consider increasing nt or decreasing nx.'],dt,h);
warning( 'MATLAB:questionable_argument',txt)
If you just embed escape characters such as \n in a warning string, it will not work:
warning('Hi there.\nPlease do not do that.')
will just print out:
Warning: hi there.\nPlease do not do that
However, if you pre-format the text using sprintf , then all the escape characters will work. For instance:
warnText = sprintf('Hi there.\nPlease do not do that.');
warning(warnText)
Produces what you want:
Warning: Hi there.
Please do not do that.
A more simple version than EBH had provided is as shown:
str1 = 'text 1';
str2 = 'text 2';
str3 = 'etc.';
str = sprintf('\n%s \n%s \n%s \n',str1,str2,str3);
warning(str)

Dear All (with many thanks in advance),
The following script has trouble reading (and therefore writing) the %s character in the file 'master.py'.
I get that matlab thinks the %s is an escape character, so perhaps an option is to modify the terminator, but I have found this difficult.
(EDIT: Forgot to mention the file master.py is not in my control, so I can't modify the file to %%s for example).
%matlab script
%===============
fileID = fopen('script.py','w');
yMax=5;
fprintf(fileID,'yOverallDim = %d\n', -1*yMax);
%READ IN "master.py" for rest of script
fileID2 = fopen('master.py','r');
currentLine = fgets(fileID2);
while ischar(currentLine)
fprintf(fileID,currentLine);
currentLine = fgets(fileID2);
end
fclose(fileID);
fclose(fileID2);
The file 'master.py' looks like this (and the problem is on line 6 'setName ="Set-%s"%(i+1)':
i=0
for yPos in range (0,yOverallDim,yVoxelSize):
yCoordinate=yPos+(yVoxelSize/2) #
for xPos in range (0,xOverallDim,xVoxelSize):
xCoordinate=xPos+(xVoxelSize/2)
setName ="Set-%s"%(i+1)
p = mdb.models['Model-1'].parts['Part-1']
# p = mdb.models['Model-1'].parts['Part-2']
c = p.cells
cells = c.findAt(((xCoordinate, yCoordinate, 10.0), ))
region = p.Set(cells=cells, name=setName)
p.SectionAssignment(region=region, sectionName='Section-1', offset=0.0, offsetType=MIDDLE_SURFACE, offsetField='', thicknessAssignment=FROM_SECTION)
i+=1
In the documentation of fprintf you'll find this:
fprintf(fileID,formatSpec,A1,...,An) applies the formatSpec to all elements of arrays A1,...An in column order, and writes the data to a text file.
So in your function fprintf uses currentLine as format specification, resulting in an unexpected output for line 6. Correct application of fprintf by providing a formatSpec, fixes this issue and doesn't require any replace operations:
fprintf(fileID, '%s', currentLine);
Your script has no trouble reading the % characters correctly. The "problem" is with fprintf(). This function correctly interpretes the percent signs in the string as formatting characters. Therefore, I think you have to manually escape every single % character in your currentLine string:
currentLine = strrep(currentLine, '%', '%%');
At least, it worked when I checked it on your example data.
Thanks applesoup for identifying my fundamental oversight - the problem is in the fprintf - not in the file read
Thanks serial for enhancing the fprintf
I have a file in the following format:
**400**,**100**::400,descendsFrom,**76**::0
**400**,**119**::400,descendsFrom,**35**::0
**400**,**4**::400,descendsFrom,**45**::0
...
...
Now I need to read, the part only in the bold. I've written the following formatspec:
formatspec = '%d,%d::%*d,%*s,%d::%*d\n';
data = textscan(fileID, formatspec);
It doesn't seem to work. Can someone tell me what's wrong?
I also need to know how to 'not use' delimiter, and how to proceed if I want to express the exact way my file is written in, for example in the case above.
EDITED
A possible problem is with the %s part of the formatspec variable. Because %s is an arbitrary string therefore the descendsFrom,76::0 part of the line is ordered to this string. So with the formatspec '%d,%d::%d,%s,%d::%d\n' you will get the following cells form the first line:
400 100 400 'descendsFrom,76::0'
To solve this problem you have two possibilities:
formatspec = %d,%d::%d,descendsFrom,%d::%d\n
OR
formatspec = %d,%d::%d,%12s,%d::%d\n
In the first case the 'descendForm' string has to be contained by each row (as in your example). In the second case the string can be changed but its length must be 12.
Your Delimiter is "," you should first delimit it then maybe run a regex. Here is how I would go about it:
fileID = fopen('file.csv');
D = textscan(fileID,'%s %s %s %s ','Delimiter',','); %read everything as strings
column1 = regexprep(D{1},'*','')
column2 = regexprep(D{2},{'*',':'},{'',''})
column3 = D{3}
column4 = regexprep(D{4},{'*',':'},{'',''})
This should generate your 4 columns which you can then combine
I believe the Delimiter can only be one symbol. The more efficient way is to directly do regexprep on your entire line, which would generate:
test = '**400**,**4**::400,descendsFrom,**45**::0'
test = regexprep(test,{'*',':'},{'',''})
>> test = 400,4400,descendsFrom,450
You can do multiple delimiters in textscan, they need to be supplied as a cell array of strings. You don't need the end of line character in the format, and you need to set 'MultipleDelimsAsOne'. Don't have MATLAB to hand but something along these lines should work:
formatspec = '%d %d %*d %*s %d %*d';
data = textscan(fileID, formatspec,'Delimiter',{',',':'},'MultipleDelimsAsOne',1);
If you want to return it as a matrix of numbers not a cell array, try adding also the option 'CollectOutput',1
eliminate punctuation
words split when meeting new line and space, then store in array
check the text file got error or not with the function of checkSpelling.m file
sum up the total number of error in that article
no suggestion is assumed to be no error, then return -1
sum of error>20, return 1
sum of error<=20, return -1
I would like to check spelling error of certain paragraph, I face the problem to get rid of the punctuation. It may have problem to the other reason, it return me the error as below:
My data2 file is :
checkSpelling.m
function suggestion = checkSpelling(word)
h = actxserver('word.application');
h.Document.Add;
correct = h.CheckSpelling(word);
if correct
suggestion = []; %return empty if spelled correctly
else
%If incorrect and there are suggestions, return them in a cell array
if h.GetSpellingSuggestions(word).count > 0
count = h.GetSpellingSuggestions(word).count;
for i = 1:count
suggestion{i} = h.GetSpellingSuggestions(word).Item(i).get('name');
end
else
%If incorrect but there are no suggestions, return this:
suggestion = 'no suggestion';
end
end
%Quit Word to release the server
h.Quit
f19.m
for i = 1:1
data2=fopen(strcat('DATA\PRE-PROCESS_DATA\F19\',int2str(i),'.txt'),'r')
CharData = fread(data2, '*char')'; %read text file and store data in CharData
fclose(data2);
word_punctuation=regexprep(CharData,'[`~!##$%^&*()-_=+[{]}\|;:\''<,>.?/','')
word_newLine = regexp(word_punctuation, '\n', 'split')
word = regexp(word_newLine, ' ', 'split')
[sizeData b] = size(word)
suggestion = cellfun(#checkSpelling, word, 'UniformOutput', 0)
A19(i)=sum(~cellfun(#isempty,suggestion))
feature19(A19(i)>=20)=1
feature19(A19(i)<20)=-1
end
Substitute your regexprep call to
word_punctuation=regexprep(CharData,'\W','\n');
Here \W finds all non-alphanumeric characters (inclulding spaces) that get substituted with the newline.
Then
word = regexp(word_punctuation, '\n', 'split');
As you can see you don't need to split by space (see above). But you can remove the empty cells:
word(cellfun(#isempty,word)) = [];
Everything worked for me. However I have to say that you checkSpelling function is very slow. At every call it has to create an ActiveX server object, add new document, and delete the object after check is done. Consider rewriting the function to accept cell array of strings.
UPDATE
The only problem I see is removing the quote ' character (I'm, don't, etc). You can temporary substitute them with underscore (yes, it's considered alphanumeric) or any sequence of unused characters. Or you can use list of all non-alphanumeric characters to be remove in square brackets instead of \W.
UPDATE 2
Another solution to the 1st UPDATE:
word_punctuation=regexprep(CharData,'[^A-Za-z0-9''_]','\n');
A=rand(10)
B=find(A>98)
How do you have text saying "There were 2 elements found" where the 2 is general i.e. it isn't text, so that if I changed B=find(A>90) it would automatically no longer be 2.
some_number = 2;
text_to_display = sprintf('There were %d elements found',some_number);
disp(text_to_display);
Also, if you wanted to count the number of elements greater than 98 in A, you should one of the following:
numel(find(A>98));
Or
sum(A>98);
sprintf is a very elegant way to display such data and it's quite easy for a person with a C/C++ background to start using it. If you're not comfortable with the format-specifier syntax (check out the link) then you can use:
text_to_display = ['There were ' num2str(some_number) ' elements found'];
But I would recommend sprintf :)
I´m working within the EDI area and would like some help with a EDIFACT macro to make the EDIFACT files more readable.
The message looks like this:
data'data'data'data'
I would like to have the macro converting the structure to:
data'
data'
data'
data'
Pls let me know how to do this.
Thanks in advance!

If you merely want to view the files in a more readable format, try downloading the Softshare EDI Notepad. It's a fairly good tool just for that purpose, it supports X12, EDIFACT and TRADACOMS standards, and it's free.
Replacing in VIM (assuming that the standard EDIFACT separators/escape characters for UNOA character set are in use):
:s/\([^?]'\)\(.\)/\1\r\2/g
Breaking down the regex:
\([^?]'\) - search for ' which occurs after any character except ? (the standard escape character) and capture these two characters as the first atom. These are the last two characters of each segment.
\(.\) - Capture any single character following the segment terminator (ie. don't match if the segment terminator is already on the end of a line)
Then replace all matches on this line with a new line between the segment terminator and the beginning of the next segment.
Otherwise you could end up with this:
...
FTX+AAR+++FORWARDING?: Freight under Vendor?'
s care.'
NAD+BY+9312345123452'
CTA+PD+0001:Terence Trent D?'
Arby'
...
instead of this:
...
FTX+AAR+++FORWARDING?: Freight under Vendor?'s care .'
NAD+BY+9312345123452'
CTA+PD+0001:Terence Trent D?'Arby'
...
Is this what you are looking for?
