Read numbers from text files into Matlab

Please, check the attached files. I want to add U1 from squarecantout to the second column in squarecantinp; U2 from squarecantout to the third column in squarecantinp; and U3 from squarecantout to the fourth column in squarecantinp. Please, note that now there are 121 total nodes, the code will also be used for some other total number of nodes.

This is what I mean: squarecantinp:

    *NODE
             1,  110.0          ,  40.0           ,  0.0            
             2,  110.0          ,  42.0           ,  0.0            
             3,  110.0          ,  44.0           ,  0.0            
             4,  110.0          ,  46.0           ,  0.0            
             5,  110.0          ,  48.0           ,  0.0   

    Sqaurecantout:

      THE FOLLOWING TABLE IS PRINTED FOR ALL NODES

Finally, in squarecantinp: I want to have have the result of the following:

*NODE
1, second column -U1  third column-U2 forth column -U3
2, second column -U1  third column-U2 forth column -U3
3, second column -U1  third column-U2 forth column -U3

"textscan" could be useful in this case.

There are more functions about reading files.
