void vsip_RCADD_f(vsip_scalar_f a, vsip_cscalar_f b, vsip_cscalar_f *r);
This function performs an addition between a real scalar and a complex scalar storing the result in the output pointer.
The operation performs:

vsip_scalar_p a: Real scalar number.
vsip_cscalar_p b: Complex scalar number.
vsip_cscalar_p* r: Pointer to the complex scalar where the result will be stored.
