Generating a random matrix which has zero entries as well

When I generate a random matrix (for example, with the following code)
bounds = [-15,10];
A = rand(m,m) * range(bounds) + bounds(1)
there is no zero entry in the matrix. Could you please tell me how can I create a random matrix which has zero entries as well?

There are several things you could do, but it depends on what properties you need your random distribution to have.
For example, you could generate the m*m random numbers as you originally did, but then generate a random number of zeros from 0:m*m, and fill them into random location in your array.
So, first, think carefully about what specific properties you need your random distribution to have, then we may be able to help you generate that distribution. It is not enough to say "numbers between -15 and 15, where some are zeros". You need to be very specific.
