How to copy only the output of a function and paste the output in another function?

Suppose the output of your first function is y1=x^2, and the input of your second function is y2=y1+10. How can I copy only the charechters "x^2" and paste that in y2?

Answer 1

[Kevin Phung]

function y1 = func1(x)
y1 = x^2
end

function y2 = func2(x)
y2 = x+10
end

y2 = func2(func1(2))  % if x=2

Thanks! I am actually looking for another approach, which is litterally copying what is in y1 and pasting the output in y2 such that y2's function could recognize the x being copied. I tried clipboard but was not successful.

Similarly to syms?

The reason I am interested in this approach is that this approach reduces the computational time by a great factor!

Not really the syms. I am actually using syms in the first function. I am also using subs() but is also somputationally expensive.

I just need that copy paste feature!
