Usage REAL X,Y
Y=FNI0e(X)
Description
FNI0ereturns the value of the modified cylindrical Bessel function of the first kind and order zero ofxscaled bye-|x|,e-|x|I0(x). The scaling is done so that the value ofI0(x) can be evaluated for arguments of large absolute value, where the value ofI0(x) may be larger than MAXREAL, the largest value representable. The value ofe-|x|I0(x) is moderate for arguments of large absolute value.
Errors
FNI0ecauses an HTBasic error if its argument is not of type REAL.
