MATLAB: How to find resultant min Graph.

minimum

hello,
I am working on a project in which i have calculated some fuel consumption values at different states of the powertrain. so now i have 4 matrices of the values.
And i want to compare them all and take out the minimum values ina resultant graph.
Let the 4 matrices be A B C D
A=[1 2 3 4 5; 2 3 4 5 6; 5 6 7 8 9]
B=[2 3 4 5 6; 5 6 7 8 0; 0 0 0 0 0]
C=[0 0 0 0 0; 1 2 0 0 0; 3 4 0 0 0]
D=[0 0 0 5 6; 0 0 0 7 5; 0 0 0 0 0]
Zero would not be considered as the Minimum value
and the resultant expected matrix is
Result=[1 2 3 4 5; 1 2 4 5 5; 3 4 7 8 9]

Best Answer

>> W = cat(3,A,B,C,D);
>> R = min(W./(W~=0),[],3)
R =
   1   2   3   4   5
   1   2   4   5   5
   3   4   7   8   9
