I used xlsread in a function. now I have another function that uses this function, and that function is used by a script. So xlsread is used 100 of times uselessly and I am getting 'out of memory' error (this maybe is not the main cause of the error). if I take xlsread into the script, the function cannot read the read variable, even it is in the workspace. How do I make the function to use the variable, without making it input variable of the function?
thanks

Yes, unfortunately, memoize was introduced in 2017a.
Actually you don't need to keep a MemoizedFunction object as a persistent variable. memoize manages its own cache persistence.
Are you reading the same file every time?

yes its the same file, it would be best if I could do it inside the script and make other functions use it. I am not willing to put it in function input because there are many variables used by different functions. But it is already good without 'persistent':
