Using Maxima for Linear Algebra


  • Assignment: row1 : [1,2,3]
  • Defining matrix: mat : matrix(row1, row2, row3)

Solving linear system

  • Use linsolve. Group the linear system in brackets, e.g.

    eq1: y = 2*x + 3 + z;
    eq2: y = 4*x + 6 + 2*z
    linsolve([eq1, eq2], [x, y])

Note solve can be used to solve both linear and non-linear systems, but with a different function protocol, e.g.

  solve([eq1, eq2])

But note that solve must have the same number of equations and unknowns.
