Compute the element-wise power function

Library

Math Functions / Math Operations

Description

The Pow block computes the value of a base raised to the power exponent. Z = Xy raises each element of X to the corresponding power in y. If one of inputs is a matrix and the other is a scalar, the scalar input is expanded to match the dimension of the non-scalar input to perform the operation. If both inputs are non-scalar, they must agree in dimension.

Data Type Support

Data type support for the block is:

  • Dimension: Inputs can be scalar, vector, or matrix. If one of the inputs is scalar and the other is a vector or matrix then the scalar input is expanded to match the other input dimension and the operation will be performed element-wise. If both inputs are non-scalar, then they must match in dimension.
  • Data Types: Input supports signals of integer type, floating point data type (double, single, and half), and signed and unsigned fixed-point type. Both inputs must be of the same data type.
  • Complex Numbers: Complex numbers are not supported.

A negative base value raised to a fractional power will result in a Not A Number (NAN) value.

Parameters

The Pow block has no parameters to set.
