Usage REAL X
COMPLEX C
C=FNS_h10(X)
Description
FNS_h10returns the value of the spherical Hankel function of the first kind and order zero ofx,h0(1)(x). The real component returned containsj0(x) and the imaginary component returned containsy0(x).
H0(1)(x) is sometime also called thespherical Bessel function of the third kind, order 0.
Errors
FNS_h10causes an HTBasic error if its argument is not of type REAL. It also causes an error if the value ofxis zero, since the imaginary component ofh0(1)(0) is infinite.
