Creates a complex number from two values in polar notation.

Given z in rectangular form z = a + bi, this node converts the polar components according to the following equation:

z = r * cos ⁡ ( t h e t a ) + i   r * sin ⁡ ( t h e t a )

r

The distance from the origin to the point, z. 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

theta

The angle for the line, r, from the origin to the point, z, in radians. 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

z

The complex number. z has the same data type as r and theta, with complex representation instead of scalar.

Data Type Changes on FPGA

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

Where This Node Can Run:

Desktop OS: Windows

FPGA: All devices

Web Server: Not supported in VIs that run in a web application
