WebWalsh-Hadamard Transform of a Signal. This example shows a simple input signal and its Walsh-Hadamard transform. x = [19 -1 11 -9 -7 13 -15 5]; y = fwht (x) y = 1×8 2 3 0 4 0 0 10 0. y contains nonzero values at locations 0, 1, 3, and 6. Form the Walsh functions with the sequency values 0, 1, 3, and 6 to recreate x. WebMATLAB apps let you see how different algorithms work with your data. Iterate until you’ve got the results you want, then automatically generate a MATLAB program to reproduce …

WebAug 25, 2024 · It is some percent faster to use a function instead of an anonymous function. This is not that much, and it was measured on an old Core2Duo. Which speed do you need? You can reduce the tolerance: Theme Copy R1 = integral (fun1, 0, inf, 'RelTol', 1e-4, 'AbsTol', 1e-6) This increases the speed by 10%, but of course it reduces the accuracy. WebApr 30, 2024 · This saves ~10% time on my PC (12.3sec down to 11.3sec). The real speed up comes from removing hold entirely, along with all of the individual plot calls! This method also doesn't touch the line formatting which will help with speed. See a previous question about updating plot data here. Simply update the plot data instead of adding plots.
