Dear GNU Radio,
This is most likely a shortcoming of how python handles significant digits, but I wanted to point out that creating a Blackmanharris window in Python and C++ result in different results.
In Python:
window = fft.blackmanharris(1024)
In c++:
const std::vector< float > window = gr::filter::firdes::window(gr::filter::firdes::WIN_BLACKMAN_HARRIS, 1024, NULL);
I have attached an image of two plots. The first plot is of the two windows on top of each other (green and blue), and the second is of their difference:
differences = python_values - cpp_values;
I was wondering why my c++ and python application were getting different results, and I have found the cause.
