Description

The atan2 block returns the output of the function atan2(y,x).

Data Type Support

Data types accepted at the inputs of the block are:

  • Dimension: Inputs can be scalar, vector, or matrix. If one of the inputs is scalar and the other is a vector or matrix then the scalar input is expanded to match the other input dimension, and operation will be performed element wise. If both inputs are non-scalar, then they must match in dimension.
  • Data Types: Input supports signals of integer type, floating point type (double, single, and half) and signed and unsigned fixed point type. Both inputs must be of the same data type.
  • Complex Number Support: No

Except for fixed-point input data type, output has the same data type as the input. For fixed point input, the output data type will be signed fixed-point with a 3-bit integer width, to be able to represent numbers between –π and π.

Parameters

The atan2 block has no parameters to set.
