How do I use same variables in different scripts?
显示 更早的评论
Hello,
Sorry for the weird English. I did my best to explain what I am struggling with....
I am wondering if you assign variable in one script, then can use those variables in another script?
For example,
In script A,
A=12;
B=23;
C=25;
D=...;
C=....;
there are tons of variables in script A.
In function script,
I want to use all variables in script A instead of assigning everything again.
thanks,

If you run script A and then script B in the same workspace, then all variables in A will remain available unless a variable is explicitly cleared or, more commonly, overwritten. This is poor workflow, though. It becomes quite difficult to troubleshoot the origin of variables and how they were changed.
A better idea is to use function input/outputs. If you're working with a lot of variables, you can store them in a structure or cell array to reduce the number of inputs/outputs and to keep your data organized.
Don't use global variable, eval, evalin, etc, to pass variables.

Agreed. I know it may seem like a lot of work to change tons of variables but now you know how to plan for this in the future and your updated functions will work so much more smoothly.
