reading input into matrix



Hello!!

I want to know how I can read the input into a matrix. I have a datalog which is shown below.

1:120:1:111:2000
1:120:1:117:2000
1:120:1:115:2000
1:120:2:113:2000
2:120:1:111:2000
2:120:1:117:2000
2:120:1:115:2000
1:120:2:104:2000
1:100:1:111:2000
1:100:1:115:2000
1:100:1:117:2000
2:120:2:113:2000

I need to read this file and convert this into a matrix as follows

1 120 1 111 2000
1 120 1 117 2000
1 120 1 115 2000
.. .. . .. ..

Can anyone suggest me how to do this in MATLAB??
I mean can u give a code which does this?
