MATLAB: Max or Min values of multidimensional array with variable number of arrays (3rd dimension)

Question

Hello, I have a upto 10 arrays of data that I "stack" using the 3rd index i.e. if my arrays are A, B, C….J etc

CombinedArray(:,:,1)=A
CombinedArray(:,:,2)=B
CombinedArray(:,:,3)=C
....
CombinedArray(:,:,3)=J    

I then want to find the max and min element wise on this multideimensional array, the problem is I dont have a fixed number for the 3rd dimension, it will always change. Is there a way to do this without using loops?

I thought the following would work but it doesn't

out1=max(CombinedArray,3)
out2=min(CombinedArray,3)
out3=mean(CombinedArray,3)

Thanks

Jason

Hi Jason,

The correct syntax is M = max(A,[],dim) and similar for min().

out1=max(CombinedArray,[],3)
out2=min(CombinedArray,[],3)
out3=mean(CombinedArray,3)
