How to speed up MATLAB codes?

As MATLAB is a mathematical language, its speed is not as fast as it is. I am wondering what common methods speed up MATLAB code execution? For example, I know that if instead of starting for loops, you can perform calculations in vector / matrix format, he / she will see the acceleration when the code runs.

I am wondering what other suggestions.

You can start looking at some ways to start thinking about vectorization here .
After this, the PDF file here , although incomplete, provides many Matlabs that give good performance.
