swix v0.1 Release Notes

Release Date: 2014-07-22 // over 9 years ago

  • A much cleaner and faster library. It calls the Accelerate library in most cases (all operators, some simple functions and all complex functions) and is nicely structured (matrix depends on ndarray depends on [Double]).

    🚦 In addition, I have implemented a complex signal processing algorithm from Matlab to iOS with this framework. The conversion was almost line for line. For example, here's a real-world example of my Matlab-iOS conversion:

    swix

    var i = abs(S) \< mu/2S[argwhere(i)] = zeros(i.n) i = argwhere(1 - i) // equivalent to notting every elementS[i] = S[i] - sign(S[i]) \* mu/2;var S0 = zeros((sm, sn)) S0["diag"] = Svar L\_new = U \*! (S0 \*! V)

    matlab

    i = abs(S) \> mu/2; S(~i) = 0; S(i) = S(i) - sign(S(i))\*mu/2; S = diag(S); S0(1:min\_snm, 1:min\_snm) = S; L\_new = U \* S0 \* V';
