Closed Host32 closed 9 years ago

Host32 commented 9 years ago

inverse(a) calculates the inverse matrix

a is a mat to be inverted

Returs a mat representing a-1

Raises an error when you try to calculate inverse of a matrix whose determinant is zero

Awesome!

Let me find out what the cost of exception throwing is in Elixir/Erlang...as I recall, I think most code doesn't really throw exceptions. So, let's see what's idiomatic, and then go from there.

Thank you again!

Merged this in and updated the hex package.

I'm fine with throwing an exception, because I think that's reasonable behavior. :)

I'll get us ready for anything left on our 1.0.0 release.

Thanks again!
