I'm having a problem with mathematica dynamic function.
I am trying to do this:
Dynamic[Refresh[randint = RandomInteger[x, {y, y}], UpdateInterval -> 0.1]]
This generates random integers in a matrix and I'm using the results to plot this matrix on a matrixplot or arrayplot, the problem happens when I try to supress it's output with ";".
The arrayplot/matrixplot simply stop working for unknown reasons. The matrix/array is ploted, but it's static.
When it's output is supressed and I call randint, I get a static output instead of a dynamic output.

I tried to invert the randint this way:
randint = Dynamic[Refresh[RandomInteger[x, {y, y}], UpdateInterval -> 0.1]]
And with this, I get other error:
"ArrayPlot::mat: "Argument {{2,1},{2,0}} at position 1 is not a list of lists."
This way seems to work. When it's output is supressed with ";" and I call randint, its output continue being evaluated, but the matrixplot/arrayplot does not accept it's output, why?
