Hi everybody,
is there a way to convert a grayscale map to a matrix? i'm able to realize the opposite operation but i've no idea on how to do this.
Thanks

What do you mean by "map"? Do you mean image, or do you mean lieterally a map, like a photo of a road map or something? What are you starting with? A grayscale image? Well that is already a matrix so there's nothing to do.

You can convert it to a grayscale truecolor matrix by using
RGB = cat(3,Grey,Grey,Grey);
If you are hoping to go from a grayscale matrix to a full-color matrix, then you cannot do that without additional information. A particular grayscale value is a projection from a whole ellipsoid of RGB color combinations.
