motopy 1.0.0

The tool of converting Matlab/Octave code TO PYthon.

Motopy

Motopy is a tool used to translate Matlab/Octave code TO PYthon.

Introduce

Motopy is a powerful tool used to translate Matlab/Octave code to PYthon. In the process of translation, the python statement generated by mopy will be executed to ensure the translated correctness of subsequent code. For example, the following Matlab/Octave code:

a = ones(1, 3);
b = a';
c = a * b;

will be translated to python code:

import numpy as np
a = np.ones((1, 3))
b = a.T
c = a @ b

The type of the variables a and b are array. So the third statement c = a * b will be translate to: c = a @ b.

install

Please use pip install motopy:

pip install motopy

Quick Start

• Motopy is very easy to use. First please prepare your Matlab/Octave files, put the script file and the function files with extetion ".m" in a folder, and ensure that your Matlab/Octave script can be run without exception. And meet the use requirements of motopy.

• Create a python script file, and input the folowing code:

  import motopy
  
  motopy.make(
      entryfile='<the script filename without extension(*.m)>',
      input_path='<the input path of *.m files>', 
      output_path='<the output path of *.py files>' 
  )
  

  You can see demo.py.

• Just run.

The Use Requirements Of Motopy

The translation will failed if your Matlab/Octave code don't satisfy the folowing requirements:

• Do not use blank spaces to separate elements in arrays and cells. The following code will make failed:

  a = [1 2 3; 4 5 6];
  c = {1 2 'abc'};
  

• The first function name in a function file must be same as the filename.

• Arrays and cells should be defined before used and allocated enough space. The following code will make failed:

  for k=1:5
      A(k) = 2*k; % The variable A is not defined before used.
  end
  

  A = []; % The variable A has not enough space.
  for k=1:5
      A(k) = 2*k; % the size of variable A will grow in iteration.
  end
