Output variable of a function as an input of another function - Problem

1 Ansicht (letzte 30 Tage)
I got two ".m" files, the first one is called "Ex_1" and the second one is called "Ex_2" as shown bellow. Output of Ex_1 must be the Input of Ex_2. How can I make function Ex_2 understand the values of a, b? Is there anyway to call variable a and b from Ex_1 in Ex_2? Thanks for your time, appreciate your help!
function [a,b]=Ex_1(dat) %dat is just a variable which I load in my program
function [freq]=Ex_2(a,b,db) %a, b is the same a, b of function Ex_1. db value doesn't matter

I don't understand your question. You are currently providing a,b,and db as inputs to function Ex_2. Why have two functions? Why not just provide Ex_1 with dat and db?

After I run Ex_1, I am typing Ex_2(a,b,0) and I am expecting the program to understand that a, b are the same values of Ex_1 (db=0 for this example). The problem is that I got an error of unrecognized function of variable 'a' that's why I am asking. I am trying to understand how functions call each other thats why I am using 2 functions.

Did you do a third procedural script calling both of them?
You could do like this in your third script.m:
[a, b] = Ex_1(data);
%% % by doing this break, you can check if a and b were loaded into your workspace
% once they were loaded, you can now call your second script by
[freq] = Ex_2(a, b, db); % assuming you´re loading db variable mannualy.
This is not necessarily the only thing you could do. You could also type these lines in your command window.
