intlut - Convert integer values using lookup table
Syntax
B = intlut(A, LUT)
Description
B = intlut(A, LUT) converts
values in array A based on lookup table LUT and
returns these new values in array B.
For example, if A is a vector whose kth
element is equal to alpha, then B(k) is equal to
the LUT value corresponding to alpha, i.e., LUT(alpha+1).
Class Support
A can be uint8, uint16,
or int16. If A is uint8,
LUT must be a uint8 vector with 256 elements. If A is uint16 or int16, LUT must
be a vector with 65536 elements that has the same class as A. B has
the same size and class as A.
Examples
A = uint8([1 2 3 4; 5 6 7 8; 9 10 11 12])
LUT = repmat(uint8([0 150 200 255]),1,64);
B = intlut(A, LUT)
