MatrixMania
This Package contains a few fundamental function which can be used for matrices.
Functions:
- matmul function
- transpose function
- rot_2D function
matmul function:
This function calculates the matrix multiplication with 2 matrices. It also checks if the matrices are compatible for multiplication.
Example:
matrix_a = [[3, 4, -1, 4],
[-2, 2, 5, 1]]
matrix_b = [[1, 3, -2],
[2, 5, 1],
[-1, 4, -4],
[2, 3, 6]]
matrix_c = matmul(matrix_a, matrix_b)
print("matrix c:")
print(tabulate(matrix_c))
Result:
matrix c:
-- -- --
20 37 26
-1 27 -8
-- -- --
transpose function:
This function transposes a matrix.
Example:
matrix = [[1, 2, 3],
[4, 5, 6]]
new_matrix = transpose(matrix)
print("transposed matrix:")
print(tabulate(new_matrix))
Result:
transposed matrix:
- -
1 4
2 5
3 6
- -
rot_2D function:
This function returns the rotation matrix for a given angle.
Example:
theta = math.pi / 2
R = rot_2D(theta)
print("rotation matrix for 90°:")
print(tabulate(R))
Result
rotation matrix for 90°:
----------- ------------
6.12323e-17 -1
1 6.12323e-17
----------- ------------
