示例1: main
int main (int argc, const char * argv[])
{
//Create an empty matrix double
MatrixDouble matrix;
//Resize the matrix
matrix.resize( 100, 2 );
//Set all the values in the matrix to zero
matrix.setAllValues( 0 );
//Loop over the data and set the values to random values
UINT counter = 0;
for(UINT i=0; i<matrix.getNumRows(); i++){
for(UINT j=0; j<matrix.getNumCols(); j++){
matrix[i][j] = counter++;
}
}
//Add a new row at the very end of the matrix
VectorDouble newRow(2);
newRow[0] = 1000;
newRow[1] = 2000;
matrix.push_back( newRow );
//Print the values
cout << "Matrix Data: \n";
for(UINT i=0; i<matrix.getNumRows(); i++){
for(UINT j=0; j<matrix.getNumCols(); j++){
cout << matrix[i][j] << "\t";
}
cout << endl;
}
cout << endl;
//Get the second row as a vector
VectorDouble rowVector = matrix.getRowVector( 1 );
cout << "Row Vector Data: \n";

cout << endl;
//Save the matrix data to a csv file
matrix.save( "data.csv" );
//load the matrix data from a csv file
