Running Stage 4.1.1
& Player v.3.1.0-svn
@ Ubuntu 12.04 LTS.
I would like to take the inverse of a nxn matrix to use in my
The issues that I encountered:
- .inverse() Eigen-library (3.1.2) doesn't allow zero values,
- Pseudo inversion doesn't seem to allow negative values
- Seldon (5.1.2) wouldn't compile for some reason
Did anyone successfully implemented an nxn matrix inversion code
that allows negative and zero-values.
Any good library recommendations?
All help would be appreciated,
Can you provide an example of a matrix you're trying to invert that
isn't working? The presence of zeros or negative numbers doesn't
necessarily have any bearing on a matrix's invertiblity, but if
you're trying to invert a singular matrix or a matrix that isn't
full rank then you're going to have issues no matter what library
