Matrix7
a library in pure python3 that allows you to use matrices and vectors easily
Setup
sudo pip install matrix7
How to use
Declarations
from matrix7 import Matrix, Vector
a = Matrix([
[1,2,3,4,5,6,7],
[101,102,103,104,105,106,107],
[201,202,203,204,205,206,207],
])
b = Vector( [2,4,7,9] )
c = Vector( [2,4,7,9] , transpose = True )printing

properties
a.size # (nb lines, nb cols)
a.trace # only for nxn matricies
a.raw # matrix or vector in normal python list format
a.gravity # only for vectorsoperations
- normal python operations are used
- Matrix or Vector object is returned
- regular matrix/vector calculation rules apply
c = a + b
c = a - b
c = a * btrasponse of matrix or vector
