I have a Matrix
K = [Mon Tue Wed Thu Fri Sat Sun]
L = [1 9 6 5 4 7 3 ;
3 5 6 4 1 8 2]
M = [K; L]
Finding the location that contain the maximum value. For example: 9 is the maximum value in this case and the column that contains it is Tue. So, how do we indicate the name of the column contain the maximum value?
Thank you!

Don't use max() - it only gives the location of the first global max, not all of them (in the case the max occurs in more than one location). Try this
maxValue = max(yourMatrix);
[rows, columns] = find(yourMatrix == maxValue)
Where yourMatrix is L or Ice or whatever you want.
If you want local maxima, use imregionalmax().

“How do i correct this?”
If it were me I would provide a valid example so that the person answering the question won’t have any trouble. Did you paste the K in command window and see what MATLAB has to say?
