Open Source Alternative to MATLAB
MATLAB licenses start around US$940 a year. GNU Octave runs your MATLAB code free; Python is the modern path.
What the paid app costs: From US$940/yr
Why switch?
Students graduate and lose their campus MATLAB license; researchers hit toolbox paywalls. Octave runs the code you already wrote, and Python's NumPy/SciPy/Jupyter stack is what industry actually hires for now.

Frequently asked questions
Will my MATLAB scripts run in Octave?
Most will, unchanged. Some specialized toolboxes have no Octave equivalent.
Should I learn Python instead?
For new work, yes. Python's scientific stack is free, vast, and the dominant skill in data jobs.
Is Octave good for coursework?
Yes, it covers the linear algebra, plotting, and scripting that courses require.
