A have a number of txt files with data, and names like ABR1998, ABR1999 etc. I am running a script that includes a "for" loop to manupulate these files and I want each time the output is saved in txt files with the same (or similar name) e.g. ABRa1998,ABRa1999 etc. The output of each loop is the "A" (see below) which is a matrix with several columns and rows of data. Could you please tell me how to do this? Thanks-K.
matfiles=dir(fullfile('N:','My Documents','MATLAB','runfilesABR', '*.txt'));
for n=1998:2005
filename = ['ABR', int2str(n), '.txt'];
A=load(filename);
XXXXXXXXXX
XXXXXXXXXX
[d,c] = find(isnan(A));
A(d,:) = [];
A
end

In the function forms of save and load, all arguments have to be strings:
filename = ['ABRa', int2str(n), '.txt'];
save(filename, 'A', '-ascii');

save(filename, A, '-ascii'); %change filename if you wish
I don't particularly understand why you're getting the list of file in the runfilesABR directory and then never you that list, though.
Can you write the code you used to generate the new filename? As the message tells you it's not a string.

Add the lines
filename
whos A
before save or put a breakpoint at save to verify that they have appropriate values
