How to get z for different x

x = [-2:0.1:2]; 
z=x.*(1-x).*(2-x).*(4-x)/((6-x)-(1-x).*(x-7));

I am getting error. Please correct my problem.

what error are you getting? what answer do you expect?

There are 41 values of x and for each x I need one z. I am not getting this. I am getting only one value of z (=-2.1203).

Answer 1

x = [-2:0.1:2];
z = x.*(1-x).*(2-x)./((6-x).*(x-7));

You just forgot a ./

Now you should have a vector

   x = [-2:0.1:2];
   z = x.*(1-x).*(2-x)./((6-x).*(x-7));
   plot(x,z)

Yes. Thanking you.

Answer 2

[Thomas]

x = [-2:0.1:2];
z=x.*(1-x).*(2-x).*(4-x)./((6-x)-(1-x).*(x-7))

You missed the . before the division to do element by element division

Presumably you want to use ./ instead of /, just like you are using .* instead of *
