【原文】：In particular, the first code example used an explicit for loop. By implementing the same functionality without the for loop, we sped it up significantly. A large part of vectorizing our Matlab/Octave code will focus on getting rid of for loops, since this lets Matlab/Octave extract more parallelism from your code, while also incurring less computational overhead from the interpreter. | 【原文】：In particular, the first code example used an explicit for loop.
