| wolffd@0 | 2 %SUBV2IND Linear index from subscript vector. |
| wolffd@0 | 3 % SUBV2IND(SIZ,SUB) returns an equivalent single index corresponding to a |

| wolffd@0 | 5 % If SUB is a matrix, with subscript vectors as rows, then the result is a |
| wolffd@0 | 6 % column vector. |

| wolffd@0 | 9 % SUBV2IND(SIZ,IND2SUBV(SIZ,IND)) == IND. |
