Use Circular Polarizer

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal).The package also includes two examples. One checks the calculation against the...

Program calculates eigenvalues, modal parameters and normalization constants for a thin circular plate with elastic edge supports. Both translational and rotational constraints are considered. User can modify the constraints and vary Poisson ratio.

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