FNH10returns the value of the Hankel function of the first kind and order zero ofx,H0(1)(x). For positive values ofx, the real component of the value returned containsJ0(x) and the imaginary component containsY0(x). For negative values ofx, the real component contains -J0(x) and the imaginary component containsY0(x).
H0(1)(x)
Arg[H0(1)(x)], degrees
Errors
FNH10causes 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 -.
