get_qr.m

dft algorithm(no fft) (matlab)

function [q, r] = get_qr(x, y)
%----------------------------------------------------------------
%   function "get_qr" computes the quotient and the remainder
%   when x is divided by y
%   i.e. (x = q*y + r)
%----------------------------------------------------------------
q = floor(x/y);
r = mod(x, y);
