Matrix Operations

Problem Statement

Perform common matrix operations.

Background

NumPy linear algebra operations:

• np.linalg.inv(A) - matrix inverse
• np.linalg.det(A) - determinant
• np.trace(A) - trace (sum of diagonal)
• A.T - transpose

Your Task

Write a function matrix_ops(mat) that computes matrix properties.

Output Format

Return a dictionary with:

• "transpose": Transposed matrix (list)
• "trace": Sum of diagonal elements
• "determinant": Determinant (rounded to 2 decimals)
• "is_symmetric": True if mat == mat.T
