Hello, i have to files .m in the same folder. One is used to run the main program and the other is used just to put the information input for the program.

p.e:

one file is the main.m and the other is info.m

info.m is similiar to this:

Volume_inicial = 900000000; Volume_final = 900000000; Volume_min = 800000000; Volume_max = 1000000000; Caudal_turb_max = 400; Caudal_bomb_max = 400;

Now, in the main.m i wanna be able to pick this data. How can i pick just Volume_inicial p.e?

Or You can declare as global variable like global Volume_inicial in your info.m file

and if you want to access particular file info, use open() command

e.g. open(D:\Users\programfiles\myfolder\info.m')

在 MATLAB Online 中打开

This is not a good idea, I would even say terrible. You can just call one script from another.

Main.m could look like this:

 %Hi, I am main
 %Load your data
 info 
 %Do your stuff

Note that once you load your info, you can save it to other variables and could even do this dynamically

If you want to get fancier, look at the run() command

You could simply run the other file, thus loading its contents in the workspace and use any variables you need.

That works, but the problem is that i have 4 info files. info1, info2, info3 and 4. They all have the same type of information but the values are different. If i load its contents into the workspace i won't be able to differentiate them and it will give me the value from the 1st file i load.

By the way, is it possible to make a while cicle to call the different info files based on their number?
