complete prompt

import numpy as np
from scipy.linalg import svd

def task_func(rows=3, columns=2, seed=0):
    """
    Generate a matrix of random values with specified dimensions and perform Singular Value Decomposition (SVD) on it.

    Requirements:
    - numpy
    - scipy.linalg.svd

    Parameters:
    - rows (int): Number of rows for the random matrix. Default is 3.
    - columns (int): Number of columns for the random matrix. Default is 2.
    - seed (int, optional): Seed for the random number generator to ensure reproducibility. Default is None.

    Returns:
    tuple: A tuple containing three elements:
        - U (ndarray): The unitary matrix U.
        - s (ndarray): The singular values, sorted in descending order.
        - Vh (ndarray): The conjugate transpose of the unitary matrix V.

    Example:
    >>> U, s, Vh = task_func(3, 2, seed=42)
    >>> print('U shape:', U.shape)
    U shape: (3, 3)
    >>> print('s shape:', s.shape)
    s shape: (2,)
    >>> print('Vh shape:', Vh.shape)
    Vh shape: (2, 2)
    """

instruct prompt

Generate a matrix of random values with specified dimensions and perform Singular Value Decomposition (SVD) on it.
The function should output with:
    tuple: A tuple containing three elements:
    U (ndarray): The unitary matrix U.
    s (ndarray): The singular values, sorted in descending order.
    Vh (ndarray): The conjugate transpose of the unitary matrix V.
You should write self-contained code starting with:
