// Option 1: Read from datafile

// Option 2: Create an empty Matrix or Vector

What to change for Assignment
Initially, change the assignment number for #define ASGN
DO NOT modify other code lines
#include "myMatrix.h"
#define ASGN 999 // enter your assignment number
#define EVAL 0 // [※ DO NOT EDIT !!!]
int main(int argc, char* argv[])
{
/* [※ DO NOT EDIT !!!] Resources file path setting for evaluation */
//std::string path = "C:/NP_Data/Assignment" + std::to_string(ASGN) + "/";
std::string path = "../../NP_Data/Assignment" + std::to_string(ASGN) + "/";
#if EVAL
path += "eval/";
#endif
...
Read data text files. You must use the given file names.
Then, apply your numerical programming algorithm.
/*==========================================================================*/
/* Variables declaration & initialization */
/*--------------------------------------------------------------------------*/
/* - You can change the variable names */
/* - However, you must use the specified txt file name */
/*==========================================================================*/
Matrix matA = txt2Mat(path, "prob1_matA");
Matrix vecb = txt2Mat(path, "prob1_vecb");
Matrix matU = txt2Mat(path, "prob1_matU");
Matrix vecd = txt2Mat(path, "prob1_vecd");
Matrix vecx_true = txt2Mat(path, "prob1_vecx_true");
// Your Code goes Here
// Your Code goes Here
/*==========================================================================*/
/* Apply your numerical method algorithm */
/*==========================================================================*/
Matrix matAdd = addMat(matA, matU); // example code

Prints vector or matrix results. You have to give a brief description for each print.
