Why this error?

Does anyone know why this error? In SampleUsage, when using the 'Input.bmp' image, there is no error (successful), but an error appears as shown when using the 'Normal-1.bmp' image.

This is a link for the code https://in.mathworks.com/matlabcentral/fileexchange/25057-texture-feature-extraction-gldm I will be appreciated if someone guides me. Thank you

Bitmap is two dimensional, right? It is a 2D matrix of integers, each integer for a pixel in the 2D plane.

Can you view that problematic BMP file using

imshow('Normal-1.bmp')

sir，may be use

im=imread('Normal-1.bmp');
if ndims(im) == 3
    im = rgb2gray(im);
end
d = 11;
[pdf1, pdf2, pdf3, pdf4] = GLDM(im, d);
