I have a raw matrix (1×8), which is generated randomly each time and it consists of 1s and 0s. I want to produce 3 1s each time and 5 0s. If there are less than 3 1s I want to randomly replace 0s with 1s until the number on 1s is 3. Suppose that I don't know the location of its element.
i.e : Α = [ 1 0 0 1 0 0 0 0 ]
Then the modified matrix A could be : [ 1 0 0 1 0 0 1 0 ]
0s have to be randomly replaced when needed and not to choose that with the lower index, in the matrix, to be replaced.
Any help could be useful. Thanks in advance!
