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.

Ran in:
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.
