**I am trying to write information to a file for some experiments. Is it possible to change the file name for each experiment without having to change the code each time?
I was trying to use a slider to change the file name but had no luck.

you can try
file-open (word "mytrack" fileName ".txt")
word strings together its arguments and converts numbers to strings in the process.

I Need to understand a very Long matlab file.
It is very tedious to put Breakpoints everywhere.
I wondered if there is an Option to track every possible variable at once ?
Something that would maybe store each variale in a text sheet and diaplays how they Change througout the code...
There are many many variables.
What I want to do is to create a scribt, where I can Input a list of variable names. The script then tracks those variable names within the program and exports them every time they Change.
Input: List of variables and programm Name (other script)
Content: Tracks variable in the Programm
Output: Table with tracked variables
Name_variable_1 |Value at line...|Value at line...|Value at line...
Name_variable_2 |Value at line...|Value at line...|Value at line...

Thanks.
You could maybe save the workspace periodically and then make a seperate MATLAB script that graphs the changes of the variables or writes out a text file for it?
I assume you're familiar with MATLAB, but just to be safe:
http://de.mathworks.com/help/matlab/ref/save.html
Just append the variable's contents to a text file or save the entire workspace and parse it later.
I want to write the file name in the gui edit text and save edit text as my filename. Than I could be able to save filename as I wish. For instance; My file is an Neural network file which could be save as *.mat file; here is my code
%network_name is my edit text
name = get(handles.network_name,'string');
name = net;
save name
But it doesn't work I can't manage file name from edit text :(
It saves as name that l wrote next to save (name.mat). Thanks for your any answer...
Why name = net;?
That aside, if you want to pass the filename as a variable to the save function, you need to use this syntax instead:
save(name)
save name is the "command form", and save('name') is the corresponding "function form". As you can see you can only give string inputs when using command form, whilst you actually want to pass a variable.
To conclude: if you are passing variables to a function, use function form.
If you want to save particular variables, use:
save(name,'net');
Note that name (which we want to be the string contained in the variable) isn't in quotes and net (the name of the variable we want to save) is.
A warning about this is actually buried in the documentation for save.
Do not use command form when any of the inputs, such as filename,
are variables.
save name
will save all of the variables in your workspace to a *.mat file called 'name'
Also your code is basically overwriting itself, line 2 sets the variable name to be a string, but then line 3 writes some data net to that variable.
I'm a little confused as to exactly what you want but I think you want to save the variable net to a mat file with the name that you read in the string from get(handles.network_name,'string')
If that is what you want to do then its just
save(get(handles.network_name,'string'), net)
If you want to save all the open variabile in the workspace then its just
save(get(handles.network_name,'string'))
So, I currently have a MATLAB script that does stuff with data and then, using a template .dat file, creates about 20 more .dat files with only a single column being changed (I've been using the dataset and export functions to read and write the files, respectively). The program that will use the .dat files, ExperimentBuilder, requires that the headers have names that start with dollar signs (for example: $image). However, when I use the dataset function in MATLAB to import the template file, I get this warning:
Warning: Variable names were modified to make them valid MATLAB identifiers.
It then replaces all the dollar signs in the variables to x_ (for example, x_image), which would be fine if it would let me change it back to the $ format. But whenever I try to using set , it just gives me this warning again and reverts it back to x_, which is unreadable by ExperimentBuilder.
I know I could just do a quick copy and paste on each file with the original headings, but I would like to know if there's a way to fix this problem in the actual code.
Thanks!
Thing is the MATLAB database uses the header names to provide access to the columns by name, this is why the header names must be valid identifiers (isvarname() states that it must starts with a letter, and contains only valid alphanumeric characters [a-zA-Z0-9_]).
The easiest solution would be manually write the header line yourself (including names starting with $), while separately exporting the data without the headers:
export(ds, ..., 'WriteObsNames',false)
(Note that dataset.export overwrites files by default, so you'll have to export first, then prepend the header line at the beginning of the file. Or if you're comfortable modifying MATLAB own functions, then go edit dataset.export and change the fopen mode from overwrite 'wt' to append 'at' mode).
I'm using MATLAB under Windows, and trying to display (dump) the contents of a text file in the command shell. It seems like overkill to open a small file in the editor, or to load the file to use disp.
Use type and specify the explicit file name (including the extension), for instance:
type('myfile.txt')
As well as type, there's also dbtype which lets you pick a start and end range to print, and shows line numbers - handy for listing source files.
I have a list of 800 words in an .rtf file in this format:
word1
word2
.
.
word799
word800
Is there any way I can create a plist of Strings out of this? I really do not want to add each word one at a time.
Thanks A Lot!
What I would do is copy and paste the list of words into a straight up text file. Then you can write a command line script in the language of your choice (I'd choose Python, for example) that will read in this text file and invoke the defaults utility from the command line to write your values. You can use the defaults utility like:
$ defaults write $PLIST_FILE $PROPERTY_NAME $VALUE # sets
