Computing the Inverse of a Triangular Matrix (tri)

tri computes the inverse of a real upper or lower triangular matrix \( A \).

Real Variant

A

(input/output) real valued TrMatrix
On entry, the triangular \( n \times n \) matrix \( A \).
On exit, if the return value equals \( 0 \), the inverse of matrix \( A \).

Complex Variant

Defined in namespace flens::lapack. Function tri with 1 template parameters.

A

(input/output) complex valued TrMatrix
On entry, the triangular \( n \times n \) matrix \( A \).
On exit, if the return value equals \( 0 \), the inverse of matrix \( A \).
