Get Values from other m.file via dropdown

In one m.file is a simple gui with a popupmenu with 4 options (C25,C35,C45,C55); In the second m.file is:

%C25
Rm=500;
Rp=600;

%C35
Rm=800;
Rp=900;

%C45
Rm=1000;
Rp=1100;

%C55
Rm=1200;
Rp=1300;

Now i need help: If i pick in the popupmenu C25, it should search "C25" in the second sheet and bring me the Values Rm=500 and Rp=600 to the First m.file. I dont know, how it works and i really need help, cause I am a matlab Rookie.

Thanks for the help. Best Regards AJ

"In the second m.file is..."

Don't use Mfiles for storing data. If you have stored this data in a .mat file then you could simply load it once and do a string comparison.

And How can i create a .mat file?

well, thank you for that. But now how i can load the variables dependent to popupmenu. When i choose C25, it need to give Rm=500 back and when i choose C35, then it need to give Rm=800 back.

One easy way would be to store the data in a structure:

S.C25.Rm = 500;
S.C25.Rp = 600;
S.C35.Rm = 800;
S.C35.Rp = 900;
S.C45.Rm = 1000;
S.C45.Rp = 1100;
S.C55.Rm = 1200;
S.C55.Rp = 1300;
save('test.mat','-struct','S')

And then to access that data from the file:

name = 'C35';
S = load('test.mat',name);
S = S.(name);
S.Rp
S.Rm

i think code corect

S.C25.Rm = 500;
S.C25.Rp = 600;
S.C35.Rm = 800;
S.C35.Rp = 900;
S.C45.Rm = 1000;
