Description

The Dot Product block generates the dot product of its two input vectors. The scalar output, y, is equal to the MATLAB operation

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.
