How can I parallelize my code matlab to speed the execution time?

Hello every one

please I need help

I program I code and it takes too much time to finish, I use large database so that s I think a reason

Anyone help me to make my code in parallel, any ideas?

thank you

If you are getting data from a microsoft file, I do not think it is about quantity of your database. But if your getting data from other softwares, it might be. Also data retrieving speed is related to your computer's RAM.

Use functions instead of scripts. Functions are generally faster.

Prefer local functions over nested functions. Use this practice especially if the function does not need to access variables in the main function.

Use modular programming.

Thank you for your answer,

Almost always the problem will not be solved using paralleization, but by writing better code. You will potentially gain far more in speed by doing so. But as you are asking it, this is not even a question about MATLAB, just a request for someone to provide a service to you, teaching you how to write the code you think you need. If you want help, you probably need to show the code you have. (Do not do so as an answer. Just attach it to your question, or to a comment.
