Initial Post — Week One

Thank you for spending your Saturday morning with your fellow students and your instructor in the applied analysis lab. I uploaded last weeks lecture slides as PDF to the OpenLab course page, including some corrections. In particular the xline function to create a vertical line did not seem to work for the older Matlab version on student computers. I provided a work around in the slides.

To recap, last week we practiced:

  • Using Matlab
    • Use Live Scrip notebooks for creating documents that contain text, code and graphs
    • Create Matlab single variables and arrays
    • Perform simple computations
    • Create a Matlab function
    • Create a graph in Matlab
  • Using complex numbers in Matlab, including:
    • Creating a complex number.
    • Cartesian and polar coordinate (Euler theorem) representation of a complex number.
    • Calculating absolute value, phase and complex conjugate of a complex number
  • RCL circuits
    • Application of Kirchhoff’s law
    • Impedance of resistor, capacitor and inductor
    • Calculate total impedance of simple circuits and resulting AC current phase shifts
    • Studying a RCL circuit simulation to find the resonance frequency

Looking forward to practice more of the above and also to continue where we left off. Please don’t be shy to raise questions if anything is unclear.

See you in class!
