matrixQR function
Generate a QR decomposition of the matrix
Examples
var a = Array2d([
Array([2.123456789, 2.123456789, 2.123456789]),
Array([2.123456789, 2.123456789, 2.123456789]),
Array([2.123456789, 2.123456789, 2.123456789])
]);
var qr = QRDecomposition(a);
Implementation
QR matrixQR(Array2d a) {
a.isMatrix();
return QR(a);
}
