Examples for Linear Algebra Methods in SymPy
The basic task in linear algebra is to solve linear equation systems:
.
Let us do this symbolically for a 3 × 3 matrix:
A = Matrix(3,3,symbols('A1:4(1:4)'))
b = Matrix(3,1,symbols('b1:4'))
x = A.LUsolve(b)
The output of this relatively small problem is already merely readable which can be seen in the following expression:
Again, the use of simplify command helps us to detect canceling terms and to collect common factors:
simplify(x)
which will result in the following output which looks much better:
Symbolic ...
