hi , I have created a folder using num2str.. but i can not save a file inside that directory as it shows error as "No such file or directory".
A=20; B=30; C=40;
xx=['A', num2str(A), 'B', num2str(B)] ;
mkdir(xx)
cfile= ['C', num2str(C)]
output2=[cfile,'.dat'];
save(['xx\', output2])

specify the path correctly inside mkdir()

I have tried using sprintf and fprintf.. but the problem is that the file is not saved inside the desired directory..
clear all
clc
U=2;
k=60;
Re=100;
sdp=['Re', num2str(Re)]
mkdir(sdp)
fnm = sprintf('U%s.dat', num2str(U));
save(fullfile(sdp,fnm), 'U')
fid2=fopen(fnm, 'w+');
fprintf(fid2,'U,k,Re\n');
fprintf(fid2,'%07.3f %07.3f %06.3f\n',U,k,Re);
fclose(fid2);
