I'm trying to create a function and it's not working, I don't know what's wrong with it?

1 view (last 30 days)
function gx = g(x)
x1 = find(x <-pi);
gx(x1)=-1;
x2 = find(x>=-pi & x<=pi);
xs = x(x2);
gx(x2)=cos(xs);
x3 = find(x>pi);
gx(x3)=-1;
end
x=-2.*pi;0.01;2.*pi;
gx=g(x)
plot (x,gx)

You need
x=-2.*pi:0.01:2.*pi;
instead of using semicolons for defining the vector.
