immultiply() - Image Processing

Z = immultiply(X,Y) multiplies
each element in array X by the corresponding element
in array Y and returns the product in the corresponding
element of the output array Z. If X and Y are real numeric
arrays with the same size and class, then Z has
the same size and class as X. If X is
a numeric array and Y is a scalar double, then Z has
the same size and class as X.If X is logical and Y is
numeric, then Z has the same size and class as Y.
If X is numeric and Y is logical,
then Z has the same size and class as X.immultiply computes each element of Z individually
in double-precision floating point. If X is an
integer array, then elements of Z exceeding the
range of the integer type are truncated, and fractional values are
rounded.If X and Y are numeric
arrays of the same size and class, you can use the expression X.*Y instead
of immultiply.

Syntax

Z = immultiply(X,Y)

Example

I = imread('moon.tif');
I16 = uint16(I);
J = immultiply(I16,I16);
imshow(I), figure, imshow(J)
