mat2gray Convert a matrix to a grayscale intensity image Syntax I = mat2gray(A,[amin amax]) I = mat2gray(A) Description I = mat2gray(A,[amin amax]) converts the matrix A to the intensity image I.The returned matrix I contains values in the range 0.0 (black) to 1.0 (full intensity or white).

I = mat2gray(A,[amin amax]) converts the matrix A to the intensity image I. The returned matrix I contains values in the range 0 (black) to 1.0 (full intensity or white). amin and amax are the values in A that correspond to 0 and 1.0 in I. I = mat2gray(A) sets theamin
