Converting C++ to Matlab code!

Can anyone be able to help me convert the C++ code below to Matlab code???

#include<iostream>
#include<cstdlib>
#include<fstream>
#include<cmath> 
using namespace std; 
int main() {
double *val = new double[56]; 
cout << "\nReading values from 'xxxx3padata.txt' file.....\n";
ifstream input;
input.open("xxxx3padata.txt"); 
if (!input) {
cout << "\nError! cannot open file";
exit(0); 
}
for (int i = 0; i < 56; i++)
input >> val[i]; 
input.close(); 
double Ra = 0, Rq = 0, Rm = 0, max = 0, min = 0; 
for (int i = 0; i < 56; i++) {
if (val[i] < min)
min = val[i]; 
if (val[i] > max)
max = val[i]; 
Ra += fabs(val[i]); 
Rq += pow(val[i], 2); 
}
Rm = max - min; 
cout << "\nThe arithmatic mean value of the measurements is: " << Ra / 56 << " microns\n"; 
cout << "\nThe root mean square average of the measurements is: " << sqrt(Rq / 56) << " microns\n"; 
cout << "\nThe maximum roughness height of the measurements is: " << Rm << " microns\n"; 
delete []val; 
return 0;
}

disp("\nReading values from 'xxxx3padata.txt' file.....")
val=importdata('xxxx3padata.txt'); 
Rmn=mean(abs(val)); 
Rms=rms(val); 
Rmnmx=max(val)-min(val); 
fprintf('\nThe arithmatic mean value of the measurements is: %f microns\n',Rmn); 
fprintf('\nThe root mean square average of the measurements is: %f microns\n',Rms);
fprintf('\nThe maximum roughness height of the measurements is: %f microns\n',Rmnmx);
clear val 

Warning: Air code, test well...
