v?I0
Computes the regular modified cylindrical Bessel function of vector elements.
Syntax
vhI0( n, a, y ); vhI0I(n, a, inca, y, incy); vmhI0( n, a, y, mode ); vmhI0I(n, a, inca, y, incy, mode); vsI0( n, a, y ); vsI0I(n, a, inca, y, incy); vmsI0( n, a, y, mode ); vmsI0I(n, a, inca, y, incy, mode); vdI0( n, a, y ); vdI0I(n, a, inca, y, incy); vmdI0( n, a, y, mode ); vmdI0I(n, a, inca, y, incy, mode);
