How to avoid to load a .mat file repeatedly in a big projet?

I wrote a function to save some pieces of data that might be used in many .m files into a .mat file. So I need to load this .mat file when I want to use these data in my functions. But there are too many functions in my project. It will spend too much time if I load the .mat file in every function.

Please tell me a method to load the .mat file as little as possible.

I'm looking forward to your answer.

Thanks!!!!!!!!!!
