compare the elements of multiple matrix and return min and max matrix

Hi everyone, I want to compare the matrixes A, B, C and find the min and max values for the same index;

A = [1 92 33;

4 15 66;

16 27 48]

B = [34 45 16;

67 38 19;

2 83 31]

C = [20 53 61;

4 17 83;

35 14 39]

and return to two matrixes such as,

Min = [1 45 16;

4 15 19;

2 14 31]

Max = [34 92 61;

67 88 83;

35 83 48]

How can I get this result? Could you please help with this?

First concatenate them, then do the min and max calls:

ABC = cat(3,A,B,C);
Min = min(ABC,[],3)
Max= max(ABC,[],3)

producing:

Min =

     1    45    16
     4    15    19
     2    14    31


Max =

    34    92    61
    67    38    83
    35    83    48

Many thanks.

FYI you can use bounds to compute Min and Max in one call.

[theMin, theMax] = bounds(ABC, 3)

@Steven — Noted. I have used bounds. I just forgot about it here.

A = [1 92 33; 
       4 15 66; 
      16 27 48];
 B = [34 45 16;
       67 38 19;
       2 83 31];
 C = [20 53 61;
       4 17 83;
       35 14 39];

D = cat(3,A,B,C);
Dmin = min(D,[],3)
Dmax = max(D,[],3)

Many thanks for the answer.
