dlmwrite Problem, text array,

I have 2 questions:

1- I want to write 2 matrices in a .csv file,

dlmwrite('csvlist.csv', T) dlmwrite('csvlist.csv', A)

I can see only A in the 'csvlist.csv' ,How can I have both of the A and T in the final output?

2- I want to have a 96 by 1 matrix

 _for i=1:1:96
      A(i,1)={'+5m'} % text
  end _

 _dlmwrite('csvlist.csv', A, 'roffset',0,'coffset',0)_

It takes 3 columns , while it should be put on one column

Thank you

Answer 1

[Azzi Abdelmalek]

to add a matrix to a file use

dlmwrite(filename, T, '-append')

 It was helpful But Azzi, When I type "dlmwrite(filename, T, '-append')" It doesn't copy T in the first row , It copies it the next row of previous matrice(row 97) ,while I need to have it in the second column and first row

Maybe you should use xlswrite?

dlmwrite() is intended for numeric values. It is possible to use it for characters, but in order to do that, you need to convert everything in the cell array to character, use a '%s' as the 'precision', and set the 'delimiter' to be empty. Which implies that all the places you want the delimiter to appear between columns, you need to put it in as one of the characters.

On the whole it is usually easier to use fopen / fprintf / fclose than dlmwrite() for strings.
