Description
The Sqrt block calculates the square root, the square root with sign, or the inverse of the square root of the input signal. One of the following functions can be selected (see parameter Function).
| Function | Description | Mathematical expression | Block icon |
|---|---|---|---|
|
Square root of the input signal |
|
|
|
Square root of the absolute value of the input signal multiplied by the sign of the input signal |
|
|
|
The inverse of the square root of the input signal |
|
|
The block icon and parameter set changes according to the function.
Ports
Input
Port_1 - input signal
scalar | vector | matrix
Input signal for calculating square root, square root with sign or inverse of square root.
The Sqrt and rSqrt functions do not support negative numbers as input.
Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64, Bool.
Support for complex numbers: none
Output
Port_1 - output signal
scalar | vector | matrix
Output signal representing the value of square root, square root with sign or inverse of square root calculated from the input signal.
If the input signal is of integer type, the output signal must be of floating point type.
Data types: Float64.
Parameters
Function - the function that the block executes
sqrt (by default) | signedSqrt | rSqrt
