Example Using the Matrix Classes
Example 2 – Using the Matrix Class
FILENAME: example2.cpp
Program:
/*
* Example program showing the use of matrix classes
* to multiply a double precision matrix by a vector.
*/
// Include the header files for double precision matrices
// and vectors:
#include <rw/math/mathvec.h>
#include <rw/math/genmat.h>
#include <iostream>
int main()
{
// Define the vector and the matrix:
RWMathVec<double> vector;
RWGenMat<double> matrix;
// Read in the vector, then the matrix:
std::cin >> vector >> matrix;
// Matrix multiply (the inner product):
RWMathVec<double> answer = product(matrix, vector);
// Print out the results:
std::cout << "answer = \n" << answer << "\n";
}
