In order to help the student become familiar with math programs used in the Engineering departments I have set up a web site dedicated to giving help with these programs.  Files located on this site were written by either myself, students, or others.  If written by students or others, there will be credit given within the file. 

Mathcad

Plotting

• Plotting a function
• Complex numbers
• Vector field and contour plotting
• Live symbolic calculations

Symbolic

• Differential Equations
• Impulse response of a first order differential eqn.
• Step response of a first order differential eqn.
• Impulse response of a second order differential eqn.
• Step response of a second order differential eqn.

Mathcad/MATLAB/Simulink

• MATLAB/Simulink simulation in Mathcad: You need three files for this example, the first is the Matchad file, the second is a MATLAB m-file and the third is a Simulink simulation file.
• Decoupled states simulation , MATLAB file, Simulink file
• FIR filter design using MATLAB in Mathcad.  The design uses fir1 in MATLAB to design the filter coefficients.  It also saves the coefficients in a file for use in a C filtering program.

DSP/Discrete-time Systems

• Aliasing
• Butterworth Filters
• Discrete Fourier Transform
• Discrete Fourier Series
• Discrete-time Fourier Transform
• Filter Design Methods
• Fourier Series/Fourier Transform
• Frequency Response
• Linear-Phase FIR Filter Design using Frequency Sampling Method
• Linear-Phase FIR Filter Design using Windowing Method
• Low Pass Filters (uses MATLAB for Butterworth filter section)
• Notch Filter (uses MATLAB)
• Pole/Zero Plot with Animation of Frequency Response Generation, you can view the animation(2.3M) or generate your own with the Mathcad file
• Digital Reconstruction
• Convolution Animation

MATLAB

• In OC's microprocessor course the project for a few years was to design from scratch a laser display system.  All that was provided was the laser scanners.  Input to the scanner sytem is +-10 volts for the X and Y deflections and a 0-5 volt input to turn the laser on and off.  When it came time to code the system there was a need to draw what was wanted to be displayed and translate that drawing into data that could be stored in memory.  To help the students I designed this script using guide from MATLAB.  The files needed are genfrm.m (the function called from MATLAB), genfrmfun.m and genfrm.mat.  Since the MC68HC11 is used in the class it outputs data that can be used with that processor.  The function genfrmfun.m can be modified for different use.
