How can I find each max element of three matrices as new matrix?

Maybe the question is a little bit confused, I'll make an example below.

Let's say I have a 3 matrices a, b, c with same size.

a = [2, 5; 6, 9];
b = [3, 3; 8, 1];
c = [5, 5; 2, 7];

How can I get the new matrix max with each max element in all three matrices?

max = [5, 5; 8, 9]

I know I could create logical matrix like a>b and then do the math, calc it out, is there any other more efficient way to do it?

You can concatenate the matrices into one 2x2x3 matrix using

d=cat(3,a,b,c)

and then use max-function to get your desired output:

maxValues=max(d,[],3)

The 3rd input to max defines along which dimension of the first input you want to find the maximum value.
