random 64x64 matrix in matlab

To randomly create a 64x64 matrix in MATLAB, you can use the rand function or the randi function.

Here's an example using rand function:

main.m
matrix = rand(64,64);
22 chars
2 lines

This will create a 64x64 matrix with elements uniformly distributed between 0 and 1.

Here's an example using randi function:

main.m
matrix = randi([0 255], 64, 64);
33 chars
2 lines

This will create a 64x64 matrix with integer elements uniformly distributed between 0 and 255.

Both rand and randi functions are useful for generating random matrices with different distributions and can be adjusted according to your specific needs.
