Not enough input arguments error in matlab
显示 更早的评论
This is my matlab code , I got Not enough input argument error in line 2 and i don't know how to fix it. Anyhelp ? Thanks in advance.
function [] = Integr1( F,a,b )
i = ((b - a)/500);
x = a;k = 0; n = 0;
while x <= b
F1 = F(x);
x = x + i;
F2 = F(x);
m = ((F1+F2)*i)/2;
k = k +m;
end
k
x = a; e = 0; o = 0;
while x <= (b - 2*i)
x = x + i;
e = e + F(x);
x = x + i;
o = o + F(x);
end
n = (i/3)*(F(a) + F(b) + 2*o + 4*e)

You forgot to give us the error message. You snipped out just a small, almost worthless, part of it. Please copy and paste the ENTIRE error message - that means ALL THE RED TEXT , not just some of it.

I ran the essence of your code (I didn’t run it as a function) and it ran for me without error.
Check the way you called your function.

I didn’t actually call your function because I didn’t want to create (and then delete) another function file.
I used:
F = @(x) sin(x).^2;
a = 0;
b = 2*pi;
I would call it as:
Integr1( F,a,b )
You’re not returning anything from your function, so it will just print out ‘k’ and ‘n’ to the Command Window.
