I am using the armadillo c++ linear library and am having difficulty with acquiring consistent results. When I print the vector, freq, those are the correct values, but when I multiply it with a scalar value, it is wrong. Even with freq * 1.0! Any suggestions would be great. The values are different from MATLAB.
mat::fixed<621,1>freq; value = 2.0 * arma::datum::pi * freq;
