FixPt Dot Product (Fixed-Point Blockset)

Generate the dot product

Description

The FixPt 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 back propagation.
Output data type: Any data type supported by the Fixed-Point Blockset.
Output scaling: 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 checked, 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 checked, fixed-point overflows saturate. Otherwise, they wrap.
Override data type(s) with doubles: If checked, the Output data type is overridden with doubles.
Log minimums and maximums: If checked, minimum and maximum simulation values are logged to the workspace.
