# calculate the maximum at each point of the grid

i have such a script where PP_all is a 100651x1 array and it derives from this formula
PP_all=1-((1-P_1_4).*(1-P_1_6).*(1-P_1_9).*(1-P_2_2).*(1-P_6).*(1-P_7).*(1- P_8).*(1-P_9 ).*(1-P_10));
in each point of the grid, therefore, the product of these values is displayed.
Now instead, in each point of the grid, I have to visualize the maximum value among all these probabilities that created me PP_all. It is as if they were a series of overlapping grids and in the end, in each point of the grid, I only display the maximum value among all the probabilities that make up PP_all and I create a new grid.
So I have to get another 100651x1 matrix (useful for visualizing the final map) where each point of the grid represents the maximum value among all the probabilities P_1_4, P_1_6,P_2_2...P_10.
Can someone help me?

I noticed that if I use only two probabilities
C= max(P_0_1,P_0_3);
I get the result I want, that is an array from 100651x1.
the problem is that the values to insert in parenthesis are not 2 but many more. anyone can help me?

PP_temp = [P_1_4, P_1_6, P_1_9, P_2_2, P_6, P_7, P_8, P_9, P_10];
PP_max = max(PP_temp,[],2);
