Description
The Dot Product block generates the dot product of its two input vectors. The scalar output, y, is equal to the MATLAB operation
y = sum(conj(u1).*u2 )
where u1 and u2 represent the vector inputs. If both inputs are vectors, they must be the same length. The elements of the input vectors may be real- or complex-valued signals of data type double. The signal type (complex or real) of the output depends on the signal types of the inputs.

To perform element-by-element multiplication without summing, use the Product block.
Data Type Support
A Dot Product block accepts and outputs signals of type double.
