testup_package

A Python package for matrix operations.

Features

• Matrix transpose
• Matrix multiplication
• Matrix inverse
• Matrix rank

Installation

pip install testupackage

Or install from source:

git clone https://github.com/yourusername/testup_package.git
cd testup_package
pip install -e .

Usage

from testup_package import transpose, matrix_multiply, inverse, rank

# Matrix transpose
m = [[1, 2, 3], [4, 5, 6]]
print(transpose(m))
# [[1. 4.]
#  [2. 5.]
#  [3. 6.]]

# Matrix multiplication
a = [[1, 2], [3, 4]]
b = [[5, 6], [7, 8]]
print(matrix_multiply(a, b))
# [[19. 22.]
#  [43. 50.]]

# Matrix inverse
m = [[1, 2], [3, 4]]
print(inverse(m))
# [[-2.   1. ]
#  [ 1.5 -0.5]]

# Matrix rank
print(rank([[1, 2], [2, 4]]))  # 1 (singular matrix)
print(rank([[1, 0], [0, 1]]))  # 2 (full rank)

API Reference

transpose(matrix)

Return the transpose of a matrix.

• Parameters: matrix - Input matrix (list of lists or numpy array)
• Returns: Transposed matrix as numpy array

matrix_multiply(a, b)

Multiply two matrices.

• Parameters: a, b - Input matrices
• Returns: Product matrix as numpy array
• Raises: ValueError if dimensions are incompatible

inverse(matrix)

Return the inverse of a square matrix.

• Parameters: matrix - Square matrix to invert
• Returns: Inverse matrix as numpy array
• Raises: ValueError if matrix is not square or is singular

rank(matrix)

Return the rank of a matrix.

• Parameters: matrix - Input matrix
• Returns: Rank as integer
