How can i observe a 3 dimensional matrix(hdr) using pcolor command?

I have with me,

file={'img1.jpg','img2.jpg','img3.jpg','img4.jpg','img5.jpg'};
hdr = makehdr(file);

hdr is 1728x2592x3 single matrix

I want to display this image file in pseudocolor.

my aim is to get the light intensity values. What shall i do?

It is possible that all of the values are small and so black might be appropriate. You can experiment with.

imagesc(rgb2gray(hdr));
colormap(gray(256))

You cannot get “actual” luminance values from RGB values without photometric calibration. rgb2gray() will give you relative luminance, subject to a number of assumptions (assumptions about linearity of the detector, assumptions about relative intensity of spectral bands, assumptions about the
