Method Details
- normF
  
  public static double normF(ZMatrixRMaj a)
  
  Computes the Frobenius matrix norm:
  
  normF = Sqrt{ ∑_i=1:m ∑_j=1:n { a_ij²} }
  
  This is equivalent to the element wise p=2 norm.
  
  Parameters:
  
  a - The matrix whose norm is computed. Not modified.
  
  Returns:
  
  The norm's value.
