if(name == 'kevin'){

This is quite wrong,

Firstly Make name into a C-styled array as in char name[30]
Then, you should use double quotes (") and not (').
...

To read the matrix.

Open the file.

while(!infile.eof())
{
string x;
infile>>x;
dosomethingwith(x);
}

SOUNDS LIKE MISSION IMPOSSIBLE.

This will self destruct in 5-4-3-2-1 BOOM!!! :)
