## sinht

Sinh by tau approximation.

Sinh by tau approximation.

[F, e, n] = sinht(A)

F = sinht(A) approximates sinh(A) by the tau method.

x = itau object.

A = any matrix.

F = polynomial approximation of sinh(M) in [a, b] evaluated (with orthovalM) in argument M = matrixM(x) = M(x). (double matrix).

schursolver and orthovalM.
