directory created with num2str

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])

Try using sprintf()

[Ribhu]

it saves the file but does not save it nside the directory..

[madhan ravi]

specify the path correctly inside mkdir()

Answer 2

[Ribhu]

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);
