grp2idx - Grouping variable to index vector
Syntax
[G,GN] = grp2idx(group)
Description
[G,GN] = grp2idx(group) creates
an index vector G from the grouping variable group. (See Grouped Data.) The variable group can be a categorical variable,
a numeric vector, a character matrix (with each row representing a
group name), or a cell array of strings stored as a column vector.
The result G is a vector taking integer values
from 1 up to the number of unique entries in group. GN is a cell array of names such that GN(G) reproduces s (with the exception
of any differences in type).
