Many functions in MATLAB® operate on categorical arrays
in much the same way that they operate on other arrays. A few of these
functions might exhibit special behavior when operating on a categorical
array. If multiple input arguments are ordinal categorical arrays,
the function often requires that they have the same set of categories,
including order. Furthermore, a few functions, such as
require that the input categorical arrays are ordinal.
The following table lists notable MATLAB functions that operate on categorical arrays in addition to other arrays.
