Creating Variable Output Filename

Hi, I have a script that generates a pdf full of plots.

I would like the output filename *.pdf file to be automatically named according to a variable which contains a date and title

How can I insert a variable filename?

This is the code which saves everything into a pdf:

ps2pdf('psfile', 'myfile.ps', 'pdffile', 'filename.pdf', 'gspapersize', 'a4')

Thanks,

psfilename = sprintf('myfile%s.ps', datestr(TheDate, 'yyyymmdd') );
ps2pdf('psfile', psfilename, 'pdffile', 'filename.pdf', 'gspapersize', 'a4')

Thanks, I tried this, it didn't work

I tried this instead, it works for a simple text filename but not if I want to insert a value from an array:

pfilename = ['sdsgafdsgf' '.pdf'];

ps2pdf('psfile', 'myfile.ps', 'pdffile', pfilename, 'gspapersize', 'a4')

When I try insert raw(3) - which is the value from an array containing the date:

>> raw(3)

ans = 

      '09/07/2012 23:22:01'

.. I get this error:

??? Error using ==> fopen
Invalid filename.

Error in ==> ps2pdf>LocalParseArgs at 199
                pdf_fid = fopen(param_value,'w');

Error in ==> ps2pdf at 105
   gsData = LocalParseArgs(varargin{:});

Error in ==> Final_Combined at 2398
ps2pdf('psfile', 'myfile.ps', 'pdffile', pfilename, 'gspapersize', 'a4')

I understand this date - 09/07/2012 23:22:01 - might not be in the correct format but it doesn't work even for text from an array

Thanks

How do you insert raw(3) ? The fact that raw(3) shows quotation marks on output tells us that raw is a cell array, and the third string in it would be accessed by raw{3} rather than raw(3) .

Great! That worked thanks.

My next dilemna is converting the date into a filename friendly format, but I'll ask that in a seperate question
