- you have saved the function as a local function (i.e. after some other code in script or after another function),
- you have saved the Mfile somewhere that is not on the MATLAB Search Path.
Why is my function not recognized?

function myEquation (x)
a = 0.4361836;
b = 0.1201676;
c = 0.937298;
r = (e^(-0.5*(x^2)))/(2*pi)
t = 1/(1+(0.3326*x))
phi = 0.5 - r*((a*t)-(b*(t^2))+(c*(t^3)))
fprintf('The value of Φ(x) is: %i', phi)
fprintf('\n')
end
This is my current code. I am trying to use it to solve for the value of phi, and then print it. However, when I try to call it from the Command Window, it just says it is an unrecognized variable or function.

"How would I call this from the command window?"
Like this:
myEquation(2)
What is probably more important is where you have saved that function:
- it must be the main function in an Mfile (i.e. it cannot be a local function or a nested function or part of a script),
- the Mfile must be on the MATLAB Search Path (simplest is to save it in the current directory).
