Hello, I am new in matlab. I have script that i need to convert to c++. What is the easiest way to do this? Here is the script

fs = 125e6;
f0 = 30e6;
 
filename = 'filename';
delimiter = ','; 
startRow = 2;   
formatSpec = '%*s%*s%*s%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%*s%*s%*s%*s%*s%*s%*s%*s%[^\n\r]';
fileID = fopen(filename,'r');
dataArray = textscan(fileID, formatSpec, 'Delimiter', delimiter, 'HeaderLines' ,startRow-1, 'ReturnOnError', false, 'EndOfLine', '\r\n');
fclose(fileID);
xx = table(dataArray{1:end-1} 
x = xx;
 [num_sample,num_chan] = size(x); 
 
for k = 1:25
end;   
cx(:,k) = (hilbert([x{:,k}])).';
 
%% 
for k = 1:num_sample 
    gen_sin(k) = sin(2*pi*f0*k/fs);
    gen_cos(k) = cos(2*pi*f0*k/fs);
end;
cgen=(complex(gen_sin,gen_cos)).'
x_down = cgen.*cx; 
Filt = designfilt('lowpassfir','FilterOrder',566,'PassbandFrequency',0.005e6, ...
         'StopbandFrequency',1.5e6, ...
         'SampleRate',fs);
fcx = filter(Filt,x_down);  %
%% Magnitude
mag_fcx=(abs(fcx));
            avmag_fcx=(zeros(1,25)); 
            for k = 1:25            
                num_averag=0;
                for kk = 300:1023
                        avmag_fcx(k)= (avmag_fcx(k)+mag_fcx(kk,k));
                end;
                avmag_fcx(k)= avmag_fcx(k)/724;
            end;
 
            for k = 1:25
               dmag_fcx(k)=avmag_fcx(1)/avmag_fcx(k); % множитель калибровочный
            end;
            log_dmag_fcx=20*log(dmag_fcx);
%% Angles
            ang_fcx=(angle(fcx))*180/pi;
 
            for k = 1:25
                for kk = 1:1024
                    if  ang_fcx(kk,k)<0
                        ang_fcx2(kk,k)=360 + ang_fcx(kk,k);
                    else ang_fcx2(kk,k)= ang_fcx(kk,k);   
                    end;            
                end;            
            end;            
 
     for kk = 1:1024
            for k = 1:25
               dang_fcx(kk,k)=ang_fcx2(kk,1) - ang_fcx2(kk,k);
               if dang_fcx(kk,k)<0
                   dang_fcx(kk,k)=360 + dang_fcx(kk,k);
               end;    
            end;
     end;       
 
%% Write to file
fid = fopen('filename1','w');
        fprintf(fid,'УГОЛ,град');
        fprintf(fid,'\t'); 
        fprintf(fid,'АМПЛИТУДА,разы');
        fprintf(fid,'\n'); 
status = fclose(fid);

MATLAB Coder is used to generate C and C++ code from MATLAB code. If it is already installed use the MATLAB coder app under Apps tab in MATLAB. It will guide you through steps to generate C++ code.
