python - 如何将numpy数组转换为Matlab矩阵？

Question

我有 testPython.py :

import numpy as np
def numpyTest():
    print("Testing numpy...")
    x = np.array([1,2,3])
    return x

我有 test.m:

clear; clc;

value = py.testPython.numpyTest()

当我运行 test.m 时，我得到:

测试 numpy...

value = 

  Python ndarray with properties:

           T: [1×1 py.numpy.ndarray]
        base: [1×1 py.NoneType]
      ctypes: [1×1 py.numpy.core._internal._ctypes]
        data: [1×24 py.buffer]
       dtype: [1×1 py.numpy.dtype]
       flags: [1×1 py.numpy.flagsobj]
        flat: [1×1 py.numpy.flatiter]
        imag: [1×1 py.numpy.ndarray]
    itemsize: 8
      nbytes: 24
        ndim: 1
        real: [1×1 py.numpy.ndarray]
       shape: [1×1 py.tuple]
        size: 3
     strides: [1×1 py.tuple]

    [1 2 3]

如何将 python numpy 数组转换为 matlab 矩阵？

Answer 1

我们必须在这里执行一些转换:

clear; clc;

value = py.testPython.numpyTest();% ndarray
pyList = value.tolist(); % ndarray -> pylist
result = cellfun(@double,cell(pyList)) %pylist-> cell array -> double array

另一种选择是通过文件传输数据，但我不喜欢它。
