C++ Armadillo :: Max and Min of matrices
---------------------------------------------------------------------------------------------------------------
Description::
This is the basic C++ program of C++ armadillo library which shows how to find minimum and maximum element of the given two matrices. It can be carried out by the help of inbuilt functions "max" and "min" in armadillo library. Both the functions "max" and "min" take two parametres.First is the input matrix 1 and the input matrix 2.

Program::
#include <iostream>
#include <armadillo>using namespace std;
using namespace arma;
int main()
{ //initialize the random generator
//Create a 4 x 4 random matrix and printing it
mat X = randu<mat>(4,4); //random matrix of size 4x4 (generared by this syntax)
mat Y = randu<mat>(4,4);
mat Z1 = arma::max(X,Y); //max
mat Z2 = arma::min(X,Y); //min
cout << "Matrix X::\n"<<endl;
cout<< X << endl; cout << "Matrix Y::\n" << endl;
cout<< Y << endl;
cout << "Matrix Z1(Max)::\n" << endl; //displaying
cout<< Z1 << endl;
cout << "Matrix Z2(Min)::\n" << endl; //displaying
cout<< Z2 << endl;
return 0;
