Da Numpy Linear Algebra in Data Analytics
Linear algebra in NumPy via np.linalg module: matrix operations for data analysis.
np.dot() performs matrix multiplication; @ operator is shorthand.
np.linalg.inv() computes matrix inverse; used in solving systems of equations.
np.linalg.eig() finds eigenvalues and eigenvectors (PCA, data compression).
np.linalg.solve() solves linear systems Ax=b efficiently.
Da Numpy Linear Algebra — Syntax
# Matrix multiplication: A @ B or np.dot(A, B) # Inverse: np.linalg.inv(A) # Eigendecomposition: eigenvalues, eigenvectors = np.linalg.eig(A) # Solve Ax=b: x = np.linalg.solve(A, b)
