Formatting cell to double

Question

I have text file in which the data is like (1,2),(3,4),1 (4,5),(6,7),1 I am reading the file in the matlab as:

A= textread('abc.txt', '%s');

the output is

A: 2x1 cell
(1,2),(3,4),1 
(4,5),(6,7),1

Anyone please help to convert this cell to double with the output

New_A= 5x2 double
1 2 3 4 1 
4 5 6 7 1

Answer 1

For your particular example, once you read the file, you can use textscan.

    A = {'(1,2),(3,4),1' 
         '(4,5),(6,7),1'};

    New_A = cell2mat(cellfun(@(line) cell2mat(textscan(line,'(%f,%f),(%f,%f),%f')), A, 'UniformOutput', 0));


New_A =

     1     2     3     4     1
     4     5     6     7     1

You can also do similar, line by line, as they are read from the file.
