循环谱分析的算法实例，简单明了，希望对你有帮助。(Cyclic spectral analysis algorithm example, simple and clear, I hope for your help.)

This code is shah s iterative algorithm for selecting primary degrees of freedom in system reduction methodology.

This does convolution of two sequences in stepwise manner according to normal understanding. sigfold.m:-fips signal 1..and changes n accordingly. sigshift.m:-shifts flipped signal from left to right to cover all overlapping sigmulti.m:-multiplies two signals at each instant of overlapping convolution.m:-it finally calculates the sum of the product
