Matrix with nested for loops

Hello!

I have to create two 20x20 matrices in which the values should be either 0 or 1 and are randomly distributed.

In one matrix the chance of getting a 1 should be 90% and in the other one it should be 95%.

I don't really understand how the nested for loop works or how the values created in the for loop get assigned to the Matrix.

I would really appreciate your help!

Thanks in advance!

You don't need loops for this. E.g.,

p = the probability
result = rand(20,20) < p;  % your matrix of 0's and 1's
