 By default, the return value `x` is a scalar, and contains the norm as evaluated over all elements of the generic-rank array \( A \). 
 If the optional `dim` argument is present, `x` is a rank `n-1` array with the same shape as \( A \) except

 Raises `LINALG_ERROR` if the requested norm type is invalid.
