如何从matrix python中移除科学符号

import numpy as np
import re

matrix = np.array([[1.23e+04, 5.67e-08], [9.87e+10, 4.56e-12]])

def remove_scientific_notation(matrix):
    # 将科学符号转换为字符串
    matrix_str = np.array2string(matrix, precision=6, suppress_small=True)
    
    # 使用正则表达式匹配科学符号并替换为空字符串
    matrix_str = re.sub(r'(?<=[\d.])e[+-]\d+', '', matrix_str)
    
    # 将字符串转换回矩阵
    matrix = np.fromstring(matrix_str, sep=' ').reshape(matrix.shape)
    
    return matrix

matrix_without_scientific_notation = remove_scientific_notation(matrix)
print(matrix_without_scientific_notation)
