Hi Jims,
I understand you wish to implement an equation inside a function defined in the same script calling it. This issue is resolved by adding two numbers, as shown in the following example.
a = 2;
b = 4;
[sum_0,sum_1] = sumEquation(a,b)
function [OUT1,OUT2] = sumEquation(x_in,y_in)
syms f(x,y)
f(x,y) = x + y;
OUT1 = f(x_in,y_in);
OUT2 = summation(x_in,y_in);
end
function out = summation(x1,y1)
syms g(x,y)
g(x,y) = x+y;
out = g(x1,y1);
end
