function [g] = FFTPF1D (X,binsize, f, P) Discrete Fourier Transform Low/High Pass Filter. % This is a simply implement of such a filter for a given 1-D data. X: the array of you data, each data point is a bin of signal binsize: the bin size in your data data f: the cutoff of wave length, P: 1, or 0, true or false : true, low pass, which eliminating higher than f frequence signals, false, high pass, which eliminating lower than f frequence signals.

The program takes the columns of an input matrix and calculates the auto and cross correlation of these columns using an fft method. The result is very similar to the xcorr function. This method could be used to evaluate the cross correlation of repeating code sequences, and other similar investigations.

Verifying and validating embedded systems comprising software and electronics is a daunting challenge, given the increasing complexity of these systems and the need to meet tight schedules. Aerospace, automotive, communications, mechatronics, and other organizations solve this challenge by starting verification as soon as they have system models and then reusing models, data, and other artifacts to verify the embedded-software or HDL implementation.
