Read .csv file to 2D array as in the file - Not one column

Please help me in the following:

I have a .csv file contains several rows and just one column .. Each cell contain long string which is separated by tab (string and integers)

For example as follows

"userid tz call_time status direction description number_prefix number in_phonebook duration"

"18672001271175066DeliveredIncomingShortmessage10495811f0c88324863d7e1a0205874c36ba4aedee737ed06708f1c2104192ad 0 0"

"18672001271175095DeliveredIncomingShort message10495811f0c88324863d7e1a0205874c36ba4aedee737ed06708f1c2104192ad 00"

Each phrase is contained in 1 cell

I want to convert it to 2d matrices in matlab in order to convert it to . mat file as follows:

Userid tz call_time status ... 186 7200 1271175

I used textread('file.csv', '%s') ans the result was as follows:

Userid tz call_time status ... 186 7200 1271175

1D ans all in just one column..

Could any one help
