Warning: Matrix is singular to working precision.

I'm not trying to inverse the matrix, why does sigularity matter?

How can I fix this?

Thank you very much!

Hi y,

In the future it would help if you copied in text rather than an image, so as to make it easy to run without retyping.

It looks like the problem is the lack of a dot in front of the last / in the expression.
