Find one Max-value from 2 columns from matrix

Hello,

i have a matrix:

M =

    3.0000    0.9873    3.0000         0
   10.0000    0.1518   10.0000    0.1255
   10.0000    0.1561   10.0000    0.1735
   10.0000    0.1619   10.0000    0.2110
   10.0000    0.0994   10.0000    0.4389
    6.0000    0.1010    6.0000    0.3090
   10.0000    0.1150   10.0000    0.2852
   

and want get one Max-Value from 2 and 4 column.

I tried:

out = max(M(:,2:2:4))

but I get two answers.

out = max(max(M(:,2:2:4)))

works, but is not nice, I think =)

Maybe there are better solution?

Answer 1

[madhan ravi]

out = max(reshape(M(:,2:2:4),1,[])
% >= 2018b
out = max(M(:,2:2:4), [], 'all')

[Nik Rocky]

out = max(reshape(M(:,2:2:4),1,[]))

works, thank you! =)
