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
