Matlab Predict function is not efficient

Matlab Predict function is not efficient...Perhaps because it is general suitable for all models. Is there a way to speed it? I am working with incremental regression kernel. Predict takes more time than updatemetricsandfit!

No code is ever as fast as users want. If you know how to make it faster, then write your own version. If your version really is better, faster, etc., then send it into a feature request to MathWorks. Or at the very least, post it on the file exchange for others to make use of too. If so, then you can contribute to making the MATLAB world a better place. It is entirely possible that you have some great insight on how to improve the code.

However, if you can't write a faster version, then maybe there is a valid reason, and all you are doing here is ranting for no purpose. Remember that your computer is not infinitely fast, and that some problems simply take time to solve.

Is it posstible that predict function is three times slower than fit?
