v?J0
Computes the Bessel function of the first kind for vector elements.
Syntax
vhJ0( n, a, y ); vhJ0I(n, a, inca, y, incy); vmhJ0( n, a, y, mode ); vmhJ0I(n, a, inca, y, incy, mode); vsJ0( n, a, y ); vsJ0I(n, a, inca, y, incy); vmsJ0( n, a, y, mode ); vmsJ0I(n, a, inca, y, incy, mode); vdJ0( n, a, y ); vdJ0I(n, a, inca, y, incy); vmdJ0( n, a, y, mode ); vmdJ0I(n, a, inca, y, incy, mode);
