The following screen dumps are from the demo application delivered with the MathXplorer/T distribution:
The top plot graph shows a signal whose frequency is modulated linearly. The bottom graph shows the power spectrum of the signal. The signal and its power spectrum are parameterized by three variables, controlled using the sliders.
This script designs an optimal FIR filter using the Remez algorithm. The desired frequency response of the filter is specified in disjoint frequency bands. Each band consists of four values: two frequencies at the endpoints of the band and corresponding response magnitudes. The filter order is the dimension of the designed FIR filter. Increasing the filter order improves the match between the desired and actual frequency responses.
This demo illustrates that inverse of random matrices have distinct patterns? Does anybody out there know why?

This demo shows some 2D and 3D plots:
This simple application consists of a prompt (where MathViews commands may be entered) and a graph widget. The graph widget will display render MathViews figures resulting from the use of plotting functions.
