Convolution can be seen as the cross-correlation of \(f(x)\) and \(g(-x)\), or \(f(-x)\) and \(g(x)\) for the real-valued functions. We have seen several posts about the cross-correlation. It is defined as the integral of the product of the two functions after one is reversed and shifted.į * g (t) = \int_ f(\tau) g(t-\tau) d\tau ConvolutionĬonvolution is a mathematical operation on two functions (\(f\) and \(g\)) that produces a third function \( conv \) that expresses how the shape of one is modified by the other. CONV FUNCTION MATLAB CODEThis can be helpful in translating the code from MATLAB to Python. In the end we will try to find how can we make the Python convolution works in the same way as the MATLAB one. If you have tried them both then you would know that its not exactly same. We will see compare the convolution functions in Python (Numpy or Scipy) with the conv function in MATLAB.
