Helper function MatInverseUpperTri () is used to compute the inverse of the R matrix that results from QR decomposition. The technique used to compute the inverse of an upper triangular or lower ...

Because the inverse function is implemented from scratch, you'll be able to modify it in many ways to meet your own needs. For example, you might want to also return the absolute value of the ...

Rao1 has shown in a lemma that a generalized inverse (g-inverse) always exists, although in the case of a singular matrix it may not be unique.

This paper presents a numerical comparison between algorithms for unconstrained optimization that take account of sparsity in the second derivative matrix of the objective function. Some of the ...

Using fifteen different variables and a blackboard-sized equation, Geek Logik author Garth Sundam has determined a formula for greatness.
