(Built-in Mathematica Symbol) Extract[expr, list] extracts the part of expr at the position specified by list. Extract[expr, {list_1, list_2, ...}] extracts a list of parts of expr. Extract[expr, list, h] ...
Flatten
(Built-in Mathematica Symbol) Flatten[list] flattens out nested lists. Flatten[list, n] flattens to level n. Flatten[list, n, h] flattens subexpressions with head h. Flatten[list, {{s_11, s_12, ...}, ...
GeodesicErosion[marker, mask] gives the fixed point of the geodesic erosion of the image marker constrained by the image mask.
HoldForm[expr] prints as the expression expr, with expr maintained in an unevaluated form.
MemoryConstrained[expr, b] evaluates expr, stopping if more than b bytes of memory are requested. MemoryConstrained[expr, b, failexpr] returns failexpr if the memory ...
