    Code 2 (F): 30% - 39% Code 1 (G): 0% - 29% The OBE system, when in its experimental stages, originally used a scale from 1 - 4 (a pass being a 3 and a '1st class pass' being above 70%), but this system was considered far too coarse and replaced by a scale from 1 to 7.

    en.wikipedia.org/wiki/Metric_signature

    The signature of a metric tensor is defined as the signature of the corresponding quadratic form. [2] It is the number (v, p, r) of positive, negative and zero eigenvalues of any matrix (i.e. in any basis for the underlying vector space) representing the form, counted with their algebraic multiplicities.

  9. Matrix sign function - Wikipedia

    en.wikipedia.org/wiki/Matrix_sign_function

    The matrix sign function is a generalization of the complex signum function ⁡ = {() >, <, to the matrix valued analogue ⁡ ().Although the sign function is not analytic, the matrix function is well defined for all matrices that have no eigenvalue on the imaginary axis, see for example the Jordan-form-based definition (where the derivatives are all zero).
