Dot Product (Fixed-Point Blockset)

Generate the dot product

Description

The Dot Product block is a masked S-function that 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 inputs. If both inputs are vectors, they must be the same length.

For a detailed description of all block parameters, refer to Block Parameters. For more information about converting from one Fixed-Point Blockset data type to another, refer to Signal Conversions.

Parameters and Dialog Box

Output data type and scaling: Specify the output data type and scaling via the dialog box, or inherit the data type and scaling from the driving block or by backpropagation.
Output data type: Any data type supported by the Fixed-Point Blockset.
Output scaling: Set the output scaling using radix point-only or [Slope Bias] scaling. These scaling modes are available only for generalized fixed-point data types.
Lock output scaling so autoscaling tool can't change it: If selected, Output scaling is locked. This feature is available only for generalized fixed-point output.
Round toward: Rounding mode for the fixed-point output.
Saturate to max or min when overflows occur: If selected, fixed-point overflows saturate.
