Matrix Input
 

I have an 8x8 matrix

and I want to enter values into the matrix.

So I would like to enter the values by Row, so that I don't have to input 64
times.

The inputs are variables. So the first Row would be

Matrix(Row = 1, ) = 1, x*5, X^3, 1, 8, ....

Is there a way to do this?

Thanks
