fn | - the math function context | |
A | - matrix on which the function must be evaluated |
B | - (optional) matrix resulting from evaluating f(A) |
If A is known to be real symmetric or complex Hermitian then it is recommended to set the appropriate flag with MatSetOption(), so that a different algorithm that exploits symmetry is used.
Scaling factors are taken into account, so the actual function evaluation will return beta*f(alpha*A).
