The command MAX will do the work. The second output is exactly the index of the max value. http://www.mathworks.com/access/helpdesk/help/techdoc/ref/max.html

I would use the 'max' function. Format it '[value index] = max(array)', where array represents the input data array, value stores the maximum value and index stores the row number at which the maximum value occurs. The index returned is the first row number in which the maximum value occurs.
I checked this using a 1x25000 array of random numbers.

You have to make another loop like this.
p=1;
i=1;
for i=1:267
if T(p,:)<C
p=p+1;
end
i=i+1;
end
p
