MATLAB: Printmat function for unknown number of rows

Example:

      M= rand(5)
      printmat(M, 'My Matrix', 'ROW1 ROW2 ROW3 ROW4 ROW5', 'FOO BAR BAZ BUZZ FUZZ' )

but suppose I don't know how many rows I will have (it depends on the user input) what can I do in this situation?

Thank's.

You can build your headers using SPRINTF; for example:

 >> M = rand(6) ;
 >> vheader = sprintf('ROW%d ', 1:size(M,1))
 vheader =
 ROW1 ROW2 ROW3 ROW4 ROW5 ROW6

(you might want to STRTRIM the output to get rid of the last white space)

You've missed a bracket

M = rand(5)
dataset({M 'FOO','BAR','BAZ','BUZZ','FUZZ'}, ...
              'obsnames', {'ROW1','ROW2','ROW3','ROW4','ROW5'})

MATLAB: How to name rows in array

Try this:

reactions =[...
         0   30.0000
   40.0000  -30.0000]
namb ={...
    'node 3'
    'node 5'}
% To be most general, find out how many rows and columns are in reactions.
[rows, columns] = size(reactions);
fprintf('Reaction Matrix   Force_x     Force_y\n');
for row = 1 : rows
  fprintf('%s            ', namb{row});
  for col = 1 : columns
    fprintf('%8.4f    ', reactions(row, col));
  end
  fprintf('\n');
end

Printed in command window is:

Reaction Matrix   Force_x     Force_y
node 3              0.0000     30.0000    
node 5             40.0000    -30.0000
