MATLAB to python conversion

I have a matlab script and its supporting function scripts. my code uses Image processing toolbox. I want to convert all to python. how can I do it ? And my python code should run independent of MATLAB. Any help .

This question should be posed in Python forum eh?

I have used libermate for matlab to python conversion. It is awesome!

I see linux commands but I'm in windows server 2012r2. Are there windows installs too or am I just missing something?

% 1. According to Piano key frequencies (https://en.wikipedia.org/wiki/Piano_key_frequencies),

% we can create its pitch by fundamental frequency.

% 2. Play twingle twingle little star as an example.

% Sessions Overview:

fs = 44100;

% rest

zero = rest(4,fs); % 1.0 sec

zeroh = rest(8,fs); % 0.5 sec

zerohh = rest(16,fs); % 0.25 sec

% eighth note as 0.5 sec

do = key(52,8,fs); %do 1

re = key(54,8,fs); %re 2

mi = key(56,8,fs); %mi 3

fa = key(57,8,fs); %fa 4

so = key(59,8,fs); %so 5

la = key(61,8,fs); %la 6

si = key(63,8,fs); %si 7

% quarter note as 1 sec

% make a song

line3 = [ so so fa fa mi mi re_4];

line4 = [ so so fa fa mi mi re_4];

song = [line1 line2 line3 line4 line5 line6];

plot(song)

sound(song,fs,24);

%audiowrite('star.wav',song,fs,'BitsPerSample',32);

function wave = key(p, n, fs)

t = 0:1/fs:4/n;

idx = 440*2^((p-49)/12);

% method 1 - orginal

wave = (sin(2*pi*idx*t));

% method 2 - exponential decreasing

% tt = 4/n:-1/fs:0;

% wave = (sin(2*pi*idx*t)).*exp(tt);

% wave = wave./max(wave);

% method 3 - triangle decreasing

% mid = (t(1)+t(end))/2;

% tri = -(abs(t-mid)-mid);

% tri = tri./max(tri);

% wave = (sin(2*pi*idx*t)).*tri;

plot(wave)

function wave = rest(n,fs)

t = 0:1/fs:4/n;

tt = 4/n:-1/fs:0;

wave = 0*sin(2*pi*t).*exp(tt);
