ifft和fft实现线性卷积,并与matlab中默认内置的conv()函数的结果对照，验证其正确性-using ifft and fft to accomplish linear conviction

探索卷积的不同的实现方法，而非用matlab中的卷积命令(explore how this can be calculated efficiently using the FFT. This entails understanding the difference between linear and circular convolution. We will explore using the FFT and compare it with a conventional direct im
