Hello all, I need to compute values for the prolate spheroidal function and compare values between different orders. From the reference guide, the function is described as *scipy.special.pro_rad1(m, n, c, x) = <ufunc 'pro_rad1'>* *Prolate spheroidal radial function of the first kind and its derivative* *Computes the prolate spheroidal radial function of the first kind and its derivative (with respect to x) for mode parameters m>=0 and n>=m, spheroidal parameter c and* *|x| < 1.0.* This tells me that x is the independent variable and that it is between -1.0 and +1.0. But, this is not the case. When I put x between 0.0 and 1.0 for example, the output is NaN. Also, I would like to know what are m and n. It is not clearly defined. I need to know which one is the order. Thanks.
