Data Format

Matrix

a = [[a11, a12, a13],
     [a21, a22, a23],
     [a31, a32, a33]] #where the value of the element is either int or float
#You can adjust the number of column and row, just make sure the length of the list is same each other

Vector

a = [[a11, a12, a13]] #where the value of the element is either int or float
#a11 represent the value of i, a12 represent the value of j, a13 represent the value of k

Frequently used function

Matrix multiplication

import algebraCalc
a = [[1, 2, 3],
     [4, 5, 6],
     [7, 8, 9]]
b = [[1],
     [2],
     [3]]
print(algebraCalc.multiplication(a, b))
# Output: [[14], [32], [50]]

Dot product

import algebraCalc
a = [[1, 2, 2]]
b = [[4, 5, 6]]
print(algebraCalc.dot(a, b))
# Output: 26
