MATLAB中怎么调用Python代码

function res = increase_piece(x)

res = {};
if isequal(x, sort(x))
    res = [res, x];
else
    diff_x = diff(x);
    node = [0, find(diff_x < 0)];
    for i = 2:length(node)
        res = [res, x( node(i-1)+1 : node(i) )];
    end

    res = [res, x( node(i)+1 : end )];
end

end

import numpy as np


def increase_piece(x):
    x = np.array(x)
    idx = np.nonzero(np.diff(x) < 0)[0] + 1
    return np.split(x, idx)

function res = call_increasing_piece_py(x)
res = cell(py.increasing_piece.increase_piece(x));
for i = 1:length(res)
    res{i} = double(res{i});
end
