I have a 15x15 array and I would like the max value from the 4th row, how would I go about doing this?

Is the 15x15 array in each cell? Or is the cell array itself 15 by 15 and something else is inside each cell, like a scalar? Have you read this: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
Have you seen cellfun()?

The cell array itself is 15x15 and there is a scalar value in each cell. Sorry for not clearing that up in the question.

a = cell2mat(yourcellarray);
out = max(a(4,:));

@Ibro Tutic: really there is no reason to store lots of scalar numeric values in a cell array, when a simple numeric array would make your code much simpler. You can see that the very first step of Andrei Bobrov's Answer is to convert the data to a numeric array, and see how easy the solution is using this numeric array.

Yep, I already addressed that. I realized that as soon as I posted the problem and did everything in terms of a numeric array. To get the max value I simply used
max(myarray(4,:)).
Thanks!
