Various expressions of Ax = b, or Gm = d if you prefer
Trying to make a basic, instructive version of Mauricio Sacchi's tutorial in various languages:
- MATLAB — the original version
- Python NumPy — finished, more or less
- Julia — started
- Lua Torch — finished, more or less
- R — I need help on this
- NumericJS — possibly ill-advised :)
The idea is to use the fundamentals of linear algebra (dot products, inverses, etc), rather than high-level functions. But where those high-level solving functions exist, we should mention and illustrate them too.
The ones that say 'finished' can certainly be improved upon!
