How to assign names for different rows of a vector?

Hello everyone,
I wanted to know if I had a vector created, for example 2 rows by 200 columns, how can I assign a name for the first row of data and then another name for the second row, essentially leaving me with two arrays?
Thanks in advance!

A vector has only one row or only one column. If your data are 2 x 200, that's a matrix. Matrices do not have a row name property so you can't assign names directly to the matrix. You can have an independent variable that stores the names such as
rownames = {'rowOne'; 'rowTwo'};
or you can put the data into a table. Tables do have a row name property.
data = rand(2,5);
rownames = {'rowOne'; 'rowTwo'};
t = array2table(data,'RowNames',rownames)
Result
t =
2×5 table
data1 data2 data3 data4 data5
________ _______ ________ _______ _______
rowOne 0.039517 0.42084 0.050453 0.86273 0.33966
rowTwo 0.88212 0.63264 0.42274 0.50203 0.43794
