subroutine | zntay (n, z, zn) |
Evaluate, by Taylor-Maclaurin expansion, the nth-derivative of the function, C(z)=cosh(sqrt(2z)), or equiavlently, of C(z)=cos(sqrt(-2z)). | |
subroutine pmat4::zntay::zntay | ( | integer(spi), intent(in) | n, |
real(dp), intent(in) | z, | ||
real(dp), intent(out) | zn ) |
Evaluate, by Taylor-Maclaurin expansion, the nth-derivative of the function, C(z)=cosh(sqrt(2z)), or equiavlently, of C(z)=cos(sqrt(-2z)).
[in] | n | integer order of the derivative |
[in] | z | real argument |
[in] | zn | returned value of the nth derivative |
