Simple Matrix Assignment

The 2nd dimension of x has 2 elements. I want to fill the first element by y.

The first element of the second dimension would look like "x[1][0]". 1 For the second dimension and 0 to get the first element. When I try "x[1][0] = y", I get an error. I don't get an error if I do "x[1][0] = y[1][0]", so is this what you are trying to do.

Wrong wrong wrong
Please pay attention to my main question. It is clear.
