Convert matrix elements from decimal to binary

Question

I have a matrix with decimal elements. I want to convert every element in this matrix to binary with a resolution of 8. What function should I use?

Answer 1

Use dec2bin:

>> dec2bin([10; 100; 255], 8)

ans =

00001010
01100100
11111111

The second parameter tells it to use at least N bits (where N==8 here).
