What Si The Use Of A Ruler

This model shows a simulation of how temperature is controlled with the use of a PID (proportional-integral-derivative) controller.

This function solves the "forward geodesic problem," which is to compute the endpoint of a geodesic (shortest-distance) path on the ellipsoidal earth, given the start point, a path length, and a starting azimuth.In response to a user request, this function numerically inverts the previously...

This scripts shows you how to obtain the name of a method or a function from within the running method/function.

This demonstration illustrates the use of a complex space vector to represent a three-phase signal . It also shows the transformation of the 3-phase signal 'ABC' into an equivalent 2-phase system 'alpha_beta'. The only restriction to the 3-phase signal is that the zero-sequence component is zero...
