## sint

Sin by tau approximation.

Sin by tau approximation.

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

F = sint(A) approximates sin(A) by the tau method . .

x = itau object.

A = any matrix.

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

schursolver and orthovalM.
