The Vector Absolute block outputs the absolute value of the input of vector type.


Super Sample Rate (SSR): This configurable GUI parameter is primarily used to control the processing of multiple data samples on each sample period. This block enables 1-D vector support for the primary block operation.

Block Parameters

Double-click the icon in your Simulink® model to open the Block Parameters dialog box.

Basic tab

This parameter allows you to specify the output precision for fixed-point arithmetic. Floating-point arithmetic output will always be Full precision.

The block uses sufficient precision to represent the result without error.
User Defined
If you do not need full precision, this option allows you to specify a reduced number of total bits and/or fractional bits.
Fixed-point Output Type

Arithmetic type:

Signed (2’s comp)
The output is a Signed (2’s complement) number.
The output is an Unsigned number.
Fixed-point Precision
Number of bits
Specifies the bit location of the binary point of the output number, where bit zero is the least significant bit.
Binary point
Position of the binary point. in the fixed-point output.
