how can i convert matlab code to arduino code or upload to arduino board

% generate a waveform

f0 =100;

fs=1000;

pw = 0.1;

pri = 1;

npulses = 100;

s = cos(2*pi*f0*(0:1/fs:pw)); % it can be any other waveform of your choice

s(round(fs*pri)) = 0; % PRI

s = repmat(s, npulses, 1); % npulses

% echo: delayed signal

tau = 0.3;

ntau = round(fs*tau);

amp = 0.5;

e = amp* circshift(s, ntau);

% add noise

sigma = 0.1;

r = s + e + sigma*randn(size(s));

y = pulsint(r);

Fn = fs/2;

Fn = 500;

Fco = 125; % Choose A Frequency > 0 & < fs/2

r_filt = lowpass(r, Fco, fs, 'ImpulseResponse','iir'); % Design An Elliptic Filter & Filter 'r'

figure

plot((0:length(s)-1)/fs, r_filt)

title('Filtered')
