I have a matrix ('positions') with 3 columns (x,y,z coordinates) and 200 rows (intracranial electodes).
I also have a character variable ('name') that contains an abbreviated name for each electrode. Is there a way to attach this column to the matrix, other than creating essentially a cell array? The goal is to ultimately export this matrix/dataset as an excel file (ie it will contain 4 columns and 200 row entries).
Thank you!

You can put the data into a table, and assign row names
For example
x = rand(5,1);
names = {'cat','dog','fish','mouse','bird'};
T = table(x,y,z,'RowNames',names)
T = 5×3 table
x y z _______ ________ ________ cat 0.13646 0.65798 0.57989 dog 0.13375 0.44793 0.50756 fish 0.12136 0.43526 0.22403 mouse 0.26111 0.068975 0.063686 bird 0.22265 0.1669 0.29217
Then to put the table into Excel
