how to select the second maximum value for an array.

A=[20 60 80 100 75 90 35 55]

with respect to A if i use the command max(A) it gives 100.

But i need to choose the second maximum value 90.

Could anyone please help me on this.

Answer 1

[ES]

B = sort(A, 'descend');
Max2 = B(2);

Answer 2

One way would be to sort the array and take the value of the second to last value.

[a,b] = sort(A);
maximum = A(b(end-1));

There are multiple ways to achieve this. I'm sure somebody will come up with a nicer oneliner, but this should do your job.
