After opening hyperspectral images(using bandread) in MATLAB, how to show one band at a time?

Commands to open or show the single bands at a time.

• %% Simple Load Hyperspectral data and Crossponding Ground Truths.
• load('Indian_pines_corrected.mat');
• load('Indian_pines_gt.mat');
• img = indian_pines_corrected;
• gt = indian_pines_gt; clear indian*
• %% Display individual Band.
• imagesc(img(:,:,i)); %% i could be any depending upon your choice raning from 1-224 in this case.
• imagesc(gt); %% Show Ground Truths.

• %% Hope this helps.

imshow() is probably the main function you want to use.
