keeping equations in different formats

Hello All.
I have a problem. In my project I have three equations which in times I use with symbolic analysis and some times with numerical values. The problem is that I cannot keep the equations as syms due to the following reasons:
1. I need to always change update the syms in different parts of the code and functions 2. Using subs or eval commands take a lot of time mainly when I use loops to change the values.
Is there a way that I could have the equations saved and call them at symbolic form or numerical form and change the variables without using subs/eval?
Thanks!
Gil,

If you want to save/load equations, then use MAT files: https://www.mathworks.com/help/matlab/matlab_env/save-load-and-delete-workspace-variables.html
Of course, that won't work if your numeric values keep changing. You'll have to use subs. Can you provide an example where subs is too slow?

I suggest that you could keep a struct, one field of which is the symbolic form, and another is the result of calling matlabFunction to transform the symbolic form to a function handle for numeric work.
