MATLAB Error - Undefined function for input arguments of type 'double'

Question

Implementing this MATLAB function

function y=myfunc(x)
    y=x^2+5*x+6;
end

is resulting in the following error.

>>myfunc(5)
Undefined function 'myfunc' for input arguments of type 'double'

I'm new to MATLAB, and any help would be appreciated!

It's probably wither in a file that is not called "myfunc.m" or not in the same folder where you are — Ander Biguri

Please edit your question to clarify where you put that function definition. — Cris Luengo

You can get results by two methods in matlab

answer= myfunc(5)

function y=myfunc(x)

y=(x^2)+(5*x)+6;

end

a) Second option is to make a new function file but name of function and file name should be same

so make a file name as myfunc and write you function code there

function y=myfunc(x)
y=(x^2)+(5*x)+6;

end

answer= myfunc(5)
