Hello everyone,
I have two parts to my question:
  1. I wanted to ask if as part of my calculations, I get an output of a 4 by 4 matrix, however I want to name each row in this matrix, how? I saw other answers on the community mentioning using tables from the beginning but I beleive I cant do that as the matrix is calculated.
  2. Also how can I plot each row in this matrix in a separate figure?
Thanks in advance!

Well, there's nothing to prevent casting the output matrix into table to use the RowNames property if that's what you want.
Whether it makes sense to use a table from the beginning depends largely on whether the data from which you start is suitable to a table or not. We have no way to judge w/ no info on the subject.
To plot, just create a loop and pass each row to plot(). Remember if do want a brand new figure to include the figure command in the loop to create a new one each pass...

A = rand(4,4) ;
var = {'row1', 'row2','row3','row4'} ;
% Table
T = table(A, 'RowNames',var) ;
% Plot
for i = 1:4
