Octave and Python (SciPy)

Some electronics questions ask you to compute a number, such as the gain of a filter at a frequency. You can answer them in Octave or in Python (SciPy), when the question offers both.

• The signal and control packages are installed. Load them yourself: put pkg load signal (or pkg load control) at the top of your file.
• Your file is main.m.
• Read input from standard input, for example v = fscanf(stdin, '%f');.
• Print results with printf or disp.

Python (SciPy)Copy Anchor Link

• Python with NumPy, SciPy and python-control.
• matplotlib is installed, but plots are not shown to you.
• Read input from input() or sys.stdin, and print results.

• Print exactly what the question asks for, such as a number with four decimals.
• Output is compared with a tolerance, so a result within the stated percentage passes.
• No other libraries are available, and you can't install packages.
• The first run can be a little slower while the libraries load.
