Converting MATLAB code to Arduino code

I need to convert this code made in MATLAB for use using the Arduino program which I believe uses C code. I am not sure how to do so and any help will be apreciated! It is for filtering data a data set.

function Hd = Lowpass_2
%LOWPASS_2 Returns a discrete-time filter object.

% MATLAB Code
% Generated by MATLAB(R) 9.5 and Signal Processing Toolbox 8.1.
% Generated on: 08-Mar-2019 11:28:05

% Equiripple Lowpass filter designed using the FIRPM function.

% All frequency values are in Hz.
Fs = 100;  % Sampling Frequency

Fpass = 0.4;             % Passband Frequency
Fstop = 0.45;            % Stopband Frequency
Dpass = 0.057501127785;  % Passband Ripple
Dstop = 0.0001;          % Stopband Attenuation
dens  = 20;              % Density Factor

% Calculate the order from the parameters using FIRPMORD.
[N, Fo, Ao, W] = firpmord([Fpass, Fstop]/(Fs/2), [1 0], [Dpass, Dstop]);

% Calculate the coefficients using the FIRPM function.
b  = firpm(N, Fo, Ao, W, {dens});
Hd = dfilt.dffir(b);

Have a look into Embedded coder and MATLAB coder.

The easiest way I find is creating a Simulink model and then deploying it on the hardware. These links should get you started:

This appears to be a ruleset for fuzzy logic. It is completely unclear to me how this answers the question of how to convert MATLAB code into Arduino code.
