%Using a script file (I)
clear;
format short g
%plot of sin with interval from [-pi,pi]
N=100;
x=linspace(-pi,pi,N)'
y=sin(x)
figure(1)
plot(x,y)
sf = 0.1
y = sin_scale(x,sf);
figure(2),
plot(x,y)
sf=[0.1 0.5 2];
N_sf = numel(sf);
sin_array = zeros(N,N_sf);
for ndx = 1: N_sf
sin_array(:,ndx) = sin_function_sf(x,sf(ndx));
end
figure(3),
plot(x,sin_array)
title(['A Sine fn; limits = [-pi pi]; Scale factors = ',num2str(sf)])
here is the code please, check this, and help me

The function is not an inbuilt function.....if you have downloaded it from somewhere, copy those functions and save. If the functions are present see to it that they are present in the same working folder.

Clearly thet are functions.
sin_scale, sin_function_sf

sin_scale = @(x,sf) sin(x) * sf;
sin_function_sf = sin_scale;
