Trigonometric Function
Perform a trigonometric function
Library
Math Operations
Description


The Trigonometric Function block performs numerous common trigonometric functions.
You can select one of these functions from the Function list: sin, cos, tan, asin, acos, atan, atan2, sinh, cosh, and tanh. The block output is the result of the operation of the function on the input or inputs.
The name of the function appears on the block icon. Simulink automatically draws the appropriate number of input ports. The block accepts and outputs real or complex signals of type double.
Use the Trigonometric Function block instead of the Fcn block when you want dimensionalized output, because the Fcn block can produce only scalar output.
Data Type Support
A Trigonometric Function block accepts and outputs real or complex signals of type double.
Parameters and Dialog Box

Function
The trigonometric function.
Output signal type
Type of signal (complex or real) to output.
Characteristics


Complex to Real-Imag
Output real and imaginary parts of complex input signal

Description
The Complex to Real-Imag block outputs the real and/or imaginary part of the input signal, depending on the setting of the Output parameter. The real outputs are of the same data type as the complex input. The input can be an array (vector or matrix) of complex signals, in which case the output signals are arrays of the same dimensions. The real array contains the real parts of the corresponding complex input elements. The imaginary output similarly contains the imaginary parts of the input elements.
Examples

Variable-Size Signal Basic Operations.How variable-size signals can be generated. It also illustrates some of the operations that can be applied to them. The purpose of this

Measure Frequency Response by Using Complex Data in Stateflow
Emulate a spectrum analyzer that measures the frequency response of a continious-time system driven by a complex sinusoidal signal.

Port_1 — Input signal
scalar | vector | matrix

Complex input signal that the block computes and outputs the real and/or imaginary part.
Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Output

Collapse all

Port_1 — Output signal
scalar | vector | matrix

Output signal that is the real and/or imaginary part of the input signal. To choose which part is output, set the Output parameter.
