WebOct 26, 2014 · Answers (1) At first: There is no evidence that vectorized code is faster in general. If a build-in function can be applied to a complete array, a vectorization is much faster than a loop appraoch. When large temporary arrays are required, the benefits of the vectorization can be dominated by the expensive allocation of the memory, when it does ... WebSimple calculations using MATLAB 7.
