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)
