Error - not enough input arguments
显示 更早的评论
Hello,
I wrote a function x3.m as follows:
function [ y ] = x3( x )
y=abs(x).^3;
end
Now I want to find the minimum of this function using fminunc.m with the initial value of 2. So I type this in the command window:
a=fminunc(x3,2)
But it returns the following error:
Error using x3 (line 4) Not enough input arguments.
Can anyone please tell me what the problem is with my code? Any help would be greatly appreciated.
Thanks, Khubaib

x3 should be entered as a function handle.
a=fminunc(@x3,2)
Or in this case:
a = fminunc(@(x) abs(x)^3,2);
