RectangularToPolar

Convert rectangular coordinates to polar coordinates

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The input values of this block are the rectangular components u_re and u_im of a phasor in two dimensions. This block calculates the length y_abs and the angle y_arg of the polar representation of this phasor.

y_abs = abs(u_re + j*u_im) = sqrt( u_re2 + u_im2 )
y_arg = arg(u_re + j*u_im) = atan2(u_im, u_re)
