From: ClauDe De on 11 May 2010 06:33 Hallo everyone, ok, I hope I can explain my problem properly... Within a loop, I would like to save my variables under a special filename which I want to take out of "B". "B" contains Instrumentnumbers (f.ex.: 2342, 2355, 16019, ... ) Here: size(B) = 1 58 The loop loads a netcdf-file and the variables are created. Now I would like to save them in a MAT-file named after the Instrumentnumber. Something like: save Instr_2342 var1 var2 var3 end of loop But I got no idea how to let it take the next number out of "B" with every loop and save it under that name. I have the feeling that this is quite simple, but I got stuck there... Thanks for your help and comments in advance!!! I really appreciate it!

I really appreciate it! Assuming your B variable is a cell array: for k = 1:length(B) % do some processing save(sprintf('%s',B{k}),'var1','var2','etc'); end

Unfortunately, B is no cell-array... my attempt: turned it into a cell-array (num2cell) But it's not working either... Got this error: ??? Error using ==> save Unable to write file : Invalid argument. mmh... any clue?! Thanks!!

> Oh, and when I run this with k = 1 > The created MAT-File is called B{k}.mat ... ups... within my testing"rage", I wrote 'B{k}'... of course the name is B{k} then... without apostrophe it's still the array- and/or argument error... |
