Matrix Inversion Algorithms Welcome to our repository! Here, we host novel and efficient matrix inversion algorithms developed as part of our research. These algorithms emphasize on triangular ...

The most probable cause is e.g. this line of code, which makes the function accept only general matrices, triangular matrices fail with the error. This is present in ...
