Deleting Multiple Elements

You can delete more than one element from a matrix, shrinking the matrix by that number of elements. To retain the rectangularity of the matrix, however, you must delete one or more entire rows or columns. For example,

mlfIndexDelete(&A, "(?,?)", mlfScalar(2),
               mlfCreateColonIndex());

produces this rectangular result:

1 4 7
3 6 9

Note    An N-dimensional subscript used in a deletion operation on the left side of the assignment statement can contain only one scalar, vector, or matrix index. The other indices must be colon indices. For example, if an array is three-dimensional and you delete row 2, you must delete row 2 from all pages.

Similar to reference and assignment, two-dimensional deletion extends to N-dimensions. If A has more than two dimensions, simply specify more than two dimensions in the index string and pass more than two index values.
