Ports
Input
#
IN_1
—
Input signal, rad
scalar | vector | the matrix
Details
The input signal is in the form of a scalar, vector or matrix. Values are considered to be expressed in radians.
| Data types |
|
| Complex numbers support |
Yes |
#
IN_2
—
the valid part of the function argument for atan2
scalar | vector | the matrix
Details
Enter the valid part of the function argument for atan2.
If for the parameter Function the value is set atan2, then 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 valid part of the function argument.
Dependencies
To use this port, set the parameter Function value atan2.
| Data types |
|
| Complex numbers support |
Yes |
Output
#
OUT_1
—
the specified trigonometric function of the input signal
scalar | vector | the matrix
Details
The result of applying the specified trigonometric function to the input signal (in radians). Each function supports:
-
Scalar operations;
-
Element-wise vector and matrix operations.
| Data types |
|
| Complex numbers support |
Yes |
#
cos
—
cosine of the input signal
scalar | vector | the matrix
Details
The cosine of the input signal in radians.
If for the parameter Function the value is set sincos, then the block shows two output ports. First output port (sin) is the sine value of the input signal. Second output port (cos) is the cosine value of the input signal.
Dependencies
To use this port, set the parameter Function value sincos.
| Data types |

# sin is the sine of the input signal
+
scalar | vector | the matrix
Details
The sine of the input signal in radians.
If for the parameter Function the value is set sincos, then the block shows two output ports. The first output port (sin) is the value of the sine of the input signal. Second output port (cos) is the cosine value of the input signal.
Dependencies
To use this port, set the parameter Function meaning sincos.

Remove protection against out-of-range input —
disable protection against input values outside the range
Logical
Details
For acos and asin select this option to disable protection against input values outside the range, which reduces redundancy.
-
When this option is unchecked, the protection is activated. The block sets the values for input data outside the range
1or-1before performing any operation. The generated code contains code for checking input values that are out of range. -
When this option is selected, the protection is disabled. The block performs all operations with the input data without any changes. The generated code does not contain any code for checking input values outside the range.
Checking this box can eliminate redundancy if the input data is already within the range.
Dependencies
To use this parameter, set for the parameter Function meaning acos and asin.
