Hi, I am wondering, in Matlab, can I preset a file name?
for example say, I am dealing with 100 data sets. Each of them will go through a long Matlab program and then I want to save the output vector in a file (1 set gives 1 file, aka, 100 output files at the end). But as I don't want to change the data-set file name at the beginning of the program, and then change save-file name at the bottom of the program for 100times, I want to do something like:
*********************
datafile = 01.dat;
AA = output_01.dat;
.
(main program)
.
save AA variable -ascii
*********************
So each time I only need to change the name of 'datafile' and the name of 'AA' at the beginning of the program. Is it possible to do this in Matlab?
Thanks.

Do you mean something like this?
datafile = '01.dat';
AA = ['output_' datafile]; % <-- Concatenate your root name with the ending
:
save(AA,'variable','-ascii');
