(Not Recommended) Set intersection for dataset array observations
The dataset
data type is not recommended. To work with heterogeneous data,
use the MATLAB^{®}
table
data type instead. See MATLAB
table
documentation for more information.

returns the common set of observations from the two arrays,
with repetitions removed. The observations in the dataset array C
are
in sorted order.

)vars
, with repetitions removed. The
observations in the dataset array C
are sorted by those
variables.
The values for variables not specified in vars
for each
observation in C
are taken from the corresponding observations in
A
. If there are multiple observations in A
that correspond to an observation in C
, then those values are taken
from the first occurrence.

such that
C = A(iA,:)
and C = B(iB,:)
. If there are
repeated observations in A

any of the previous input arguments.
