Error using dot(A,B) - size/dimension problem

Hello.
I get the error "Error using dot (line 15) A and B must be same size." (Which is dot(A,B) ) I have tried numbers of time now, and I still don't know what I am doing wrong here.
I have the normal vector. 'n' and a point 'x' in the plane and the output is 's' in my formula.
I have attempted to get same dimension with size, but it appears not to been working so well.
...
n = vector
x = point in a plane
size(x,dim)
size(n,dim)
s=x+2*(d-dot(x,n))*n;
...
Regards
Cillian

The error seems pretty clear to me your n and x are different sizes.

While the multiplication between "a" and "b" works now, I guess that "b" and "n" have different sizes and the matrix multiplication fails.
However, Cillian, it is time to stop the confused guessing. Please post the complete relevant part of the code and explain what you want to compute. It seems like there is a problem in the mathematical part already.
