matrixNormTwo function

double matrixNormTwo(
  1. Array2d a
)

Two norm return maximum singular value.

Examples

var a = Array2d([
  Array([1, 2, 3]),
  Array([1, 2, 3]),
  Array([1, 2, 3]),
]);

print(a.norm2());

/* output:
6.496425037213701
*/

Implementation

double matrixNormTwo(Array2d a) {
  return SVD(a).norm2();
}
