I would like to ask how to open Indian_pines hyperspectral image? I have used the below code.
load Indian_pines;
I=indian_pines;
I=multibandread('indian_pines',[145,145,220],'uint8=>uint8', 128,'ieee-le',{'Band','Direct',[4 3 2]});
I have a lot of erros:
Error using fopen
Invalid machine format.
Error in multibandread>parseInputs (line 309)
fid = fopen(filename,'r',byteOrder);
Error in multibandread (line 112)
info = parseInputs(filename, dims,...

indian_pines.mat is a .mat file. You use load to read it in.
Once you have read it in, there is NO reason to need to read it in again!!!!! multibandread is not used here, because you just read it in!

Dear Sir, You are right, I would like to use multibandread. Then I would like to convert to RGB and then to make SVM classification, if this would be possible.
