WebDec 3, 2024 · Convolve two arrays on Google Sheets? How can I take the convolution of two distributions on a spreadsheet such as Google Sheets? Example 1: You want to multiply two arbitrary polynomials together on a spreadsheet symbolically (e.g. 2*x^4 + x times 3*x^2 - 5 ). Example 2: Like in a board game or tabletop game, you have two 6-sided dice🎲🎲 ... Webw = conv (u,v) returns the convolution of vectors u and v. If u and v are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. w = conv (u,v,shape) returns a subsection of the convolution, as specified by shape . For example, conv (u,v,'same') returns only the central part of the convolution, the ...
