MATLAB: Do i get “Too many output arguments” when i try to multiply the function

Question

My function is

function integralCO02(t)
(2/sqrt(pi))*exp(-t^2)
end

and when I try

2*integralCO02(5)

the error message 'Too many output arguments.' comes up.

The same happens for

anyconstante = integralCO02(5)

Answer 1

You did not create an output when you declared your function.

Try this slightly modified version of your function:

function result = integralCO02(t)
result = (2/sqrt(pi))*exp(-t^2);
end

The call to it:

anyconstante = integralCO02(5)

now produces:

anyconstante =
     1.567086653101734e-11
