I am trying to read an ENVI image (.RAW) into MATLAB using the
commands below. The new image does not resemble the original image.
The size of my image is [10322,1600]. Data type is float. Has anyone
done this before? Thanks!

fid=fopen('a1_bk_sapph.raw','r');
img=fread(fid,[10322,1600],'float32');
frewind(fid);
fclose(fid);

You may want to try my m_gmt program (w3.ualg.pt/~jluis/m_gmt). It
has no manual yet but it is able to read ENVI files via a mex file
based on gdal. (use the ecran_grd program)

the raw envi image comes with no header.
first, u have to find out (in the envi header file) what is the image
format (BIP, BIL, BSQ), and than read the data accordingly.
if u have more questions, do ask.
hope this helps,
