Problem 55250. Find the minimum of the column-maximums of a matrix
Given a matrix A, find the maximum value of each column, then return the smallest of those maximum values (ie return the minimum of the column maximums).
A = [5 3 4 3;1 2 6 3;1 1 4 4];
m = minimax(A)
m =
3
Note that your function should work for matrices with one row or column (ie vectors) and scalars (in which case m = A).

@Neha Shaah: how so? If the input is a row vector, the column maximums will be the elements themselves. Hence the minimum will be the minimum of the input vector itself.
