power, .^
Fixed-point element-wise power
Syntax
Description
Examples
Raise Each Element of a Matrix to a Scalar Power
Create a fixed-point matrix and raise it to a scalar power.
A = fi([1, 3; 4, 2])
A = 1 3 4 2 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 12
C = A.^3
C = 1 27 64 8 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 48 FractionLength: 36
Input Arguments
A
— Base
scalar | vector | matrix | multidimensional array
Base, specified as a scalar, vector, matrix, or multidimensional array. Inputs
A
and B
must either be the same size or have
sizes that are compatible (for example, A
is an
M-by-N matrix and B
is a
scalar or 1-by-N row vector).
Data Types: single

| int32
| int64
| uint8
| uint16
| uint32
| uint64
| logical
| fi
Complex Number Support: Yes
B
— Exponent
scalar
Exponent, specified as a non-negative, real, integer-valued scalar.
Data Types: single

Output Arguments
C
— Power
scalar | vector | matrix | multidimensional array
Power, returned as an array with the same dimensions as the input
A
. When A
has a local fimath
object, the output C
also has the same local
fimath
object. The array power operation is always performed using
the default fimath
settings.
Extended Capabilities
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.
Usage notes and limitations:
When the exponent
B
is a variable, theProductMode
property of the governingfimath
must beSpecifyPrecision
.
HDL Code Generation
Generate Verilog and VHDL code for FPGA and ASIC designs using HDL Coder™.
Both inputs must be scalar, and the exponent input, B
, must be a
constant integer.
Version History
Introduced in R2010aR2021a: Improved numerical accuracy and generated code efficiency for fi
inputs to power, .^
Fixed-Point Designer™ now has improved numerical accuracy for fixed-point inputs to the
power
function in simulation and generated code. Additionally,
generated code is more efficient.
