Getting started¶
This section gives an example of use of matrix library and the procedure to compile it.
Example¶
#include <iostream>
#include "castor/matrix.hpp"
using namespace castor;
int main (int argc, char* argv[])
{
matrix<float> A = {{ 1.0, 2.0, 3.0, 4.0},
{ 5.0, 6.0, 7.0, 8.0},
{ 9.0, 10.0, 11.0, 12.0}};
matrix<double> B = eye(3,4);
auto C = A + B;
disp(C);
return 0;
}
This example displays the sum of two matrices with implicit cast :
2.00000 2.00000 3.00000 4.00000
5.00000 7.00000 7.00000 8.00000
9.00000 10.00000 12.00000 12.00000
Compilation¶
Command line¶
The library matrix is a header-only library. That actually means to compile program using matrix, you just have to specify to the compiler the path to the directory containing the headers. For instance, with GCC, the command to compile the above example (assuming it is contained in a file named main.cpp) :
g++ -std=c++14 -I /path/to/castor/folder main.cpp -o main
IDE¶
Simply enter the path to the directory containing the castor folder in your favorite IDE (VSCode, Xcode, CodeBlocks).
