Maximum value/number of multiple vectors from different matrices

Hello I am trying to obtain a Maximum number from multiple vectors,
Here is an example
A = [7 12 12 10 177 55];
B = [3 6 6 4 21 30];
C = [0.024 0.042 0.042 0.034 0.61 0.19];
I Haven’t used Octave in a while so would greatly appreciate some help.Thanks!

Is this what you want?
q=max([A, B, C])

Yes, that was helpful, thank you very much.
I have been trying many times but without [ ].
