y

An input to this operation.

This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.

Data Type Changes on FPGA

When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.

datatype_icon

x

An input to this operation.

This input supports scalar numbers and fixed-size 1-dimensional arrays of numbers.

Data Type Changes on FPGA

When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.

datatype_icon

atan2(y,x)

Result of the operation. atan2(y,x) falls in the range [-pi, pi].

When x or y are complex, the following equation defines atan2(y,x):
a tan 2 ( y , x ) = 1 2 i ln ( i + y x i y x )
