I have a 3 dimensional array in ENVI format (bsq format). I wonder how can I import it in Matlab.I used the following code but it's for writing a new array and not for reading an exisiting array into Matlab. I apperciate your help in advance.
rows=743; cols=210; bands=6;
filename = 'myfile';
fid = fopen(filename, 'w', 'ieee-le');
fwrite(fid, 1:rows*cols*bands, 'float');
fclose(fid);
im1 = multibandread(filename, [rows cols bands], ...
'float', 0, 'bsq', 'ieee-le' )

I found a page with documentation that suggests that the multibandread() command should work, as long as you match datatypes and byte order properly.

Thanks for the comment. the page you refered to, is ENVI's help file. There's nothing about that function.

If you have Image Processing Toolbox you could easily use imread to read the image and imshow to display it.

thanks for the comment. the format of my image is bsq (ENVIformat). I tried imread function but it couldn't recognize the format.
