Undefined function or variable 'impact'.

Hey, Ive been stuck in this script for weeks. dont know what's wrong is it the varible "impact".

because it works for my friend but it dont work with me

function [thetadotdot] = acceleration(r,g,a_c,theta,k0)
thetadotdot = ((g.*r.*sin(theta))+(a_c.*r.*cos(theta)))./k0^2;
end

clc;
clear;
g = 9.81;
theta = 33;
vel = zeros(1,10);
tim = zeros(1,10);
AC = zeros(1,10);
i = 0;
for a_c = 1*g:g:10*g
    i = i + 1;
    AC(i)=a_c;
    I = impact(a_c,theta);
    vel(i) = I;
    tim(i) = 0.75/I;
end
figure
subplot(1,2,1)
plot(AC,vel)
title('Velocity vs acc.');
xlabel('acc');
ylabel('Velocity');
subplot(1,2,2);
plot(AC,tim)
title('Time vs acc.');
xlabel('acc');
ylabel('Time');

Make sure impact function is present within the matlab path. You can try >> which impact

Hi Raad,

Make sure the function 'impact' is present in the matlab path. You can try

>> which impact

Then add the folder in which it is present to the MATLAB path and that will solve.

Thanking you.
