hello i have this code :

clear all;

clc;

Values_Of_The_Circuit(1).P_out_sepic=100;

Values_Of_The_Circuit(1).V_desire=18;

Values_Of_The_Circuit(1).R=Values_Of_The_Circuit(1).V_desire*Values_Of_The_Circuit(1).V_desire;

i want that R=V_desire*V_desire is there a way to write it i an short way insted of Values_Of_The_Circuit(1).V_desire ?

Well, yes: Use a nicer name for the struct:

V(1).P_out_sepic = 100;
V(1).V_desire    = 18;
V(1).R           = V(1).V_desire ^ 2;

Names of variables should be meaningful and short. If you keep the functions small (magnitude of 100 lines), using shorter names can be more useful (less prone to typos) than including a short story into the name. But add clear and meaningful comments instead.

Writing "V_desire" only would work only, if this is the variable, you want to access. But you want "V(1).V_desire". If the struct V is a scalar, "V.V_desire" would be sufficient, but if V is a array with more than 1 element, "V(1).V_desire" is the only way to access it.
