Converting between Classes

Converting images from one class to another is a common operation.
The general syntax for class conversion is

B = class_name(A);

Following are the valid class conversions with their input and output

Name	Converts Input to:	Valid Input Image Data Classes
im2uintB	uintB	logical, uintB, uint16, int16, single,and double
im2uint16	uint16	logical, uintB,uint16, int16, single,and double
im2double	double	logical, uintB, uint16, int16, single,and double
im2single	single	logical, uintB, uint16, int16, single,and double
mat2gray	double in the range [0, 1]	logical, uintB, intB, uint16, int16,uint32, int32, single, and double
im2bw	logical	uintB, uint16,int16, single, and double

Example

>> A = [0.12,0.22,0.32;1.23,1.33,1.43]

A =

    0.1200    0.2200    0.3200
    1.2300    1.3300    1.4300

>> B = im2uint8(A)   % Converts to the following as

B =

   31   56   82
  255  255  255
