I am writing a function to search a record from sheet2 and return value to sheet1. I use the Find function and it works for most of the case. However, I encounter below issus.
The FIND function only support one matching key only. If I have more than one value to match, it didn't work.
Sometime, the search value may have space like "Key1 ". Then, if I search the word by "Key1", no record return. I can't use the wildcard search as I need exact match except the space.
To solve this, should I simply use a For loop to search the result instead of FIND? I have to loop through every row. I am not sure the performance is okay or not.
No related to FIND. As I need to copy the value as well as the backgroup color. I use the return cells.interior.colorindex to set the field. But the color is a little bit different. For example, the original is light green but it turn out to become darken color. I check both field has same colorindex. Any idea?

Thanks,
see anyone has idea how to resolve it.

I am working on a large project in Xcode. I'm wanting to search, using the Find Navigator (See Below), for all arrays regardless of their name. I only care about any array that has this format, someArray[index].
Some Examples That Should Match
people[12]
section[0].rows[0]
Should Not Match
people[index]
section[section].row[row]
The regex should only return arrays, it should not return any dictionaries or other types that are not a subscripted array.
Why am I doing this? Well, it appears there have been some issues within our app where devs have not properly handled index out of bounds errors or nil values. There are far too many arrays for me to manually go through line by line to find them, so this is the best option I've come up with and it may not even be possible. If anyone has other recommendations, please feel free to share.
You can create a regex to match any word followed by another word with optional period enclosed by brackets. Something like:
\w+\[\w+(\.\w+)?\]
For more info about the regex above you can check this link
For numbers only use \d+ instead:
\w+\[\d+\]

In the Running Total Fields, how do you set up a Distinct Count that includes blank values as one of your conditions?
Just found a solution. It's:
isnull({table.column})
Before asking, that's what I tried, but it wasn't working. So for people like me who tried that and it didn't work, that's because you have multiple conditions in your Running Total, and for whatever reason it only works when you edit your syntax and place that near the top of your conditions instead of the bottom. Don't know the reason, but it's working now.
I'd recommend replacing the field you're currently totaling with a new Formula. Something that doesn't ever come up blank, like:
If ISNULL {yourfieldhere} THEN "Blank" ELSE {yourfieldhere}
or if it's an empty string:
If {yourfieldhere}="" THEN "Blank" ELSE {yourfieldhere}
You can replace "Blank" with whatever suits you, even just an empty " " space or 0. But then it's at least something distinct to be counted.
I am trying to convert my documents into vector-space format using doc2mat
On the website, it says I can use my specified text file where words are white-space separated or on multiple lines. So, I use some code similar to this one:
./doc2mat -mystoplist=stopword.txt -skipnumeric mydocuments.txt myvectorspace.txt
However, when I check the output .clabel file, it still has stop words that's in stopword.txt.
I really do not know how to do this. Someone help me out please? Thank you!
There's one important thing I should remember: I should include ALL the unwanted words in my stop list. This is somewhat difficult since there's always some variations available...
For example, if I want to exclude method I add it to my list. However, the resulting vocabulary may also contain method since there are words like methodist, methods, etc. Then doc2mat by default stems these words and I will still get method in the output.
Another thing is to make sure that "-nostop" option must be provided for user-specified stop list.
I am defining a variable in the beginning of my source code in MATLAB. Now I would like to know at which lines this variable effects something. In other words, I would like to see all lines in which that variable is read out. This wish does not only include all accesses in the current function, but also possible accesses in sub-functions that use this variable as an input argument. In this way, I can see in a quick way where my change of this variable takes any influence.
Is there any possibility to do so in MATLAB? A graphical marking of the corresponding lines would be nice but a command line output might be even more practical.
You may always use "Find Files" to search for a certain keyword or expression. In my R2012a/Windows version is in Edit > Find Files..., with the keyboard shortcut [CTRL] + [SHIFT] + [F].
The result will be a list of lines where the searched string is found, in all the files found in the specified folder. Please check out the options in the search dialog for more details and flexibility.
Later edit: thanks to #zinjaai, I noticed that #tc88 required that this tool should track the effect of the name of the variable inside the functions/subfunctions. I think this is:
very difficult to achieve. The problem of running trough all the possible values and branching on every possible conditional expression is... well is hard. I think is halting-problem-hard.
in 90% of the case the assumption that the output of a function is influenced by the input is true. But the input and the output are part of the same statement (assigning the result of a function) so looking for where the variable is used as argument should suffice to identify what output variables are affected..
There are perverse cases where functions will alter arguments that are handle-type (because the argument is not copied, but referenced). This side-effect will break the assumption 2, and is one of the main reasons why 1. Outlining the cases when these side effects take place is again, hard, and is better to assume that all of them are modified.
Some other cases are inherently undecidable, because they don't depend on the computer states, but on the state of the "outside world". Example: suppose one calls uigetfile. The function returns a char type when the user selects a file, and a double type for the case when the user chooses not to select a file. Obviously the two cases will be treated differently. How could you know which variables are created/modified before the user deciding?
In conclusion: I think that human intuition, plus the MATLAB Debugger (for run time), and the Find Files (for quick search where a variable is used) and depfun (for quick identification of function dependence) is way cheaper. But I would like to be wrong. :-)
Im having some trouble with using text as an condition for a while loop, currently the basic coding is:
result=struct('val','yes');
while result.val=='yes'
result.val=input('more digits?');
end
So as you see, what Im trying to do is keeping the loop going as long as the user types in 'yes'. But thats one of the probelmes I am having; Is there a way to get rid of the need to write the ''(e.g yes instead of 'yes')? Secondly, when I run the code it gives me the error message "Error using == ,Matrix dimensions must agree.". I realise this have to do with the word yes being longer than no, but I don't know how to fix it. It's not really an issue though considering its the the program ends anyway, but it is an annoyance I would like to get rid off.
To compare strings, use strcmp, or strcmpi to ignore case. It will handle comparison of different length strings. For example:
strcmpi(result.val,'yes')
If you want to search for a substring, such as just a 'y', at the beginning of the input, consider strncmpi (strncmpi(result.val,'y',1)) or just check the first character (result.val(1)).
