Function Names

horizontal

Description

Converts a vector (set) or (vertical 1D) matrix (nested set) to a horizontal 1D-matrix. In other words: The 2-level set structure is flattened and then all of contents is pushed into a 2nd level so the result looks always like {{ a,b,c,... }}.

The matrices may contain contents of all data types and not just numerals.
