Let me guess, that you have a [M x N x 5] DOUBLE array containing the greyscale values for 5 different wavelength. Then a "gradient" can be calculated between the different channels, or it can be the direction of the largest or average change of intensity, or a lot of other values....
x = gradient(a) 11111 In the above example, the function calculates the gradient of the given numbers. The input arguments used in the function can be vector, matrix or a multidimensional array and the data types that can be handled by the function are single, double. It also supports the...
