can a random number generator be used in a matrix?

I'm trying to make a minesweeper game in matlab so I set up a matrix A=zeros(10) and I wanted to know if I could write the code so that 1s will be randomly scattered throughout the matrix whenever the code is run.

The randi function would be good for that, and thresholding the rand function would also work.
M = randi([0 1],10)
M = 10×10
1 1 1 0 1 1 1 1 1 0 1 0 1 0 0 1 0 1 0 0 1 0 0 0 0 0 1 1 0 0 1 0 1 0 1 1 0 0 0 1 0 0 1 0 0 1 1 0 1 1 0 0 1 0 0 0 0 1 1 0 0 1 0 1 1 1 0 1 0 1 0 1 1 1 1 0 0 0 1 0 0 0 1 1 0 1 1 0 0 1 1 1 0 0 1 1 1 1 1 0
M = +(rand(10)>=0.5)
M = 10×10
0 0 1 1 0 1 0 1 0 0 0 1 1 0 1 1 1 1 1 1 0 1 0 0 0 1 1 1 1 1 1 0 0 1 1 0 0 1 1 1 0 0 1 1 1 1 0 1 1 1 1 1 1 1 0 0 1 0 1 1 1 1 0 1 0 0 0 0 0 0 1 1 1 0 0 0 0 0 1 0 0 1 1 1 1 1 0 0 0 1 0 0 1 0 0 1 1 1 0 1
Experiment to get appropriate results.

Do you want a certain probability of each cell being a mine or do you want a certain fixed number of mines? In the latter case, use randperm to identify a few locations where the mines are located then fill in those locations with linear indexing.
