How to take inverse cosine in matlab
WebDec 1, 2014 · I have some Matlab code of the following form: syms theta x theta = acos(x) This returns a single solution for theta. However, I want to return the complete solution … WebFeb 7, 2012 · Your code works fine, but it is designed to only accept a 2D array, just like dct2() in Matlab. Since your arr is a 3D array, you want to do. D = dct2(arr[...,2]) As mentioned in my comment, instead or reinventing the wheel, use the (fast) built-in dct() from the scipy package. The code from the link in my comment effectively provides you this:
