matlab调用python的各种方法举例子详解

% 添加函数模块路径, 如果路径不在则搜索不到
py.sys.path().append('fun/to/path')
mymod = py.importlib.import_module('py_name')  % 不要带py后缀,不然报错
a = mymod.print_num(1)
disp(a)

# num.py
def print_num(num):
   return num

% 添加函数模块路径, 如果路径不在则搜索不到
py.sys.path().append('fun/to/path')
mymod = py.importlib.import_module('num')  % 不要带py后缀,不然报错
a = mymod.print_num(1)
disp(pwd)
disp(a)

% 引入Python模块
% py.math;
% 调用Python模块中的函数
result = py.math.sqrt(4);
disp(result);  % 显示结果

a = py.list({'This','is a','list'});
disp(a);
b = py.textwrap.wrap('This is a string');
disp(b);

% 返回值的
pyrunfile("fun.py")

# 定义num.py的函数
def print_num(num=1):
  print("执行print_num函数")
  return num
if __name__ == "__main__":
  b = print_num(3)
  print("hello world!")

% a string, cellstr or a char array
% 添加当前python的文件路径
py.sys.path().append('fun/to/path')
% 调用这个函数
pyrunfile("num.py")

% 返回值的
out_vulue = pyrunfile("fun.py", "var_nam")

# num.py
def print_num(num=1):
  return num
if __name__ == "__main__":
  b = print_num(3)

% a string, cellstr or a char array
% 添加当前python的文件路径
py.sys.path().append('fun/to/path')
% 调用这个函数
myListFile = pyrunfile("num.py", "b")

# 已经定义的num.py
def print_num(num=1):
  c = 1
  print("执行print_num函数")
  return num
if __name__ == "__main__":
  a =  print_num(2)
  b = print_num(3)
  print("hello world!")

[a, b, c] = pyrunfile("num.py", ["a", "b", "c"]);

% 返回值的
out_vulue = pyrunfile("fun.py argv1 argv2 ...argvn", "var_nam")

# num.py
import sys
def print_num(num=1):
  ans = num+1
  return ans
if __name__ == "__main__":
  arg = sys.argv[1]
  print(type(arg))
  b = print_num(int(arg))
  print(b)

b = pyrunfile("num.py 1", "b");

% 返回值的
out_vulue = pyrunfile("fun.py", "var_nam", arg1=v1, arg2=v2)

# num.py
def print_num(num=1):
  ans = num+1
  return ans
if __name__ == "__main__":
  num1= x
  num2 = y
  a = print_num(num1)
  b = print_num(num2)
  print(a)
  print(b)

[a, b] = pyrunfile("num.py", ["a", "b"], x=1, y=2);
