Difficulty with nested loop and arrays

I'm fairly new to matlab. I'm just started learning about nested loops and need some help. I have an array of random numbers and i need to create a nested loop to read the random data one by one by row and then columns and assign the data to a new variable. Can anyone help me with this? Thanks.

    for RowIndex = 1:...
       for ColIndex = 1:...
          CurrentValue = MyMatrix(RowIndex,ColIndex)
       end
    end

I leave it for you to figure out what should be at the ellipses. Hint:
