I have a loop like this:
for i=1:no
%some calculations
fid = fopen( c:\out.txt , wt );
%write something to the file
fclose(fid);
end
I want data to be written to different files like this:
i=1, data is written to out1.txti=2, data is written to out2.txti=3, data is written to out3.txtDoing out + i does not work. How can this be done?
Yet another option would be the function SPRINTF:
fid = fopen(sprintf( c:\out%d.txt ,i), wt );
filename = strcat( out , int2str(i), .txt );
Did you try:
int2str(i)
More simply:
for i=1:no
%some calculations
fid = fopen([ c:out int2str(i) .txt ], wt );
%write something to the file
fclose(fid);
end
PS. I don t believe Matlab strings need escaping except for (unless it s a format string for *printf style functions)
