INT2BIN Convert Integer Arrays to Binary

Section: Array Generation and Manipulations

Usage

Computes the binary decomposition of an integer array to the specified number of bits. The general syntax for its use is

   y = int2bin(x,n)

where x is a multi-dimensional integer array, and n is the number of bits to expand it to. The output array y has one extra dimension to it than the input. The bits are expanded along this extra dimension.

Example

The following piece of code demonstrates various uses of the int2bin function. First the simplest example:

--> A = [2;5;6;2]
A = 
  <int32>  - size: [4 1]
 
Columns 1 to 1
 2  
 5  
 6  
 2  
--> int2bin(A,8)
ans = 
  <logical>  - size: [4 8]
 
Columns 1 to 8
 0  0  0  0  0  0  1  0  
 0  0  0  0  0  1  0  1  
 0  0  0  0  0  1  1  0  
 0  0  0  0  0  0  1  0  
--> A = [1;2;-5;2]
A = 
  <int32>  - size: [4 1]
 
Columns 1 to 1
          1  
          2  
         -5  
          2  
--> int2bin(A,8)
ans = 
  <logical>  - size: [4 8]
 
Columns 1 to 8
 0  0  0  0  0  0  0  1  
 0  0  0  0  0  0  1  0  
 1  1  1  1  1  0  1  1  
 0  0  0  0  0  0  1  0
