Question: Matrixplot - options

I'm using matrixplot to plot a matrix 10X10. 
But I want it to be shown only the interval between column 2..6 and row 1..10.

I tried to:

matrixplot(M, row = 1..10, column = 2..6, heights = histogram, axes = boxed) 
But gave error!
***I can not reset the Matrix for 10x5.

Please Wait...
