MATLAB: File import

Question

Hallo,

I would like to import in Matlab a set of data, which originally is expressed in 4 columns: ex:

            1490               3               2              0.
           20094               1               2              0.
           66779               4               2              0.
           14293               3               2              0.
           53990               1               2              0.  
           61190               4               2              0.

I want it to be imported as one column excluding the 4th columnm, and combining the 3 numbers for each row in one number like this:

            1490*3*2             
           20094*1*2              
           66779*4*2              
           14293*3*2              
           53990*1*2              
           61190*4*2

How can I use the function textscan to do it? are there other ways to do it?

Thanks.

Sami

Save your text in a file called 'test.txt'

a=importdata('test.txt');
a=a(:,1:3);
b=sprintf('%d%d%d\n',a')
c=str2num(b)
