function c = dot(a,b,dim)

%DOT  Vector dot product.

%   C = DOT(A,B) returns the scalar product of the vectors A and B.

%   A and B must be vectors of the same length.  When A and B are both

%   column vectors, DOT(A,B) is the same as A'*B.

%

%   DOT(A,B), for N-D arrays A and B, returns the scalar product

%   along the first non-singleton dimension of A and B. A and B must

%   have the same size.

%

%   DOT(A,B,DIM) returns the scalar product of A and B in the

%   dimension DIM.

%

%   Class support for inputs A,B:

%      float: double, single

%

%   See also CROSS.
