Ports

Input

# IN_1 — input signal, rad
scalar | vector | matrix

Details

An input signal in the form of a scalar, vector or matrix. Values are considered to be expressed in radians.

Data types

Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64, Bool.
Complex numbers support

Yes

# IN_2 — the real part of the function argument for atan2
scalar | vector | matrix

Details

Enter the real part of the function argument for atan2.

If the parameters for . Function is set to atan2, the block shows two input ports. The first input port (In_1) is the imaginary part of the function argument. The second input port (In_2) is the real part of the function argument.

Dependencies

In order to use this port, set the parameter Function value atan2.

Data types

Float16, Float32, Float64, Int8, Int16, Int32, Int64, UInt8, UInt16, UInt32, UInt64, Bool
Complex numbers support

Yes

Output

# OUT_1 — specified trigonometric function from the input signal
scalar | vector | matrix

Details

The result of applying the specified trigonometric function to the input signal (in radians). Each function supports:

  • Scalar operations.

  • Elemental vector and matrix operations.

Data types

Float64.
Complex numbers support

Yes

# cos — cosine of input signal
scalar | vector | matrix

Details

The cosine of the input signal in radians.

When the parameters are set to Function is set to sincos, the unit displays two input ports. The first input port (sin) is the sine value of the input signal. The second input port (cos) is the cosine value of the input signal.

Dependencies

To use this port, set the parameters to Function value sincos.

Data types

Float64.
Complex numbers support

Yes
