e.g a =
4 2 8
5 9 1
3 10 17
maximum will be 17 for the entire array and 3 will be the min value along the row of 17.

[v_max,jj] = max(max(a,[],2));
out_min = min(a(jj,:));
or
[ii,~] = find(max(a(:))==a);
out = min(a(ii,:));

x=[4 2 8;5 9 1;3 10 17];
[M,I] = max(x(:)); % find maximum element in the entire matrix
[I_row, I_col] = ind2sub(size(x),I);% convert matrix position to matrix indices
x_min = x(I_row,:); % extract the row containing maximum value
x_min = min(x_min); % minimum of that row

% creating the matrix
A =randi([1,20],5,7)
% getting the maximum value of the matrix
% to get minimum value use min() function
b = max(A)
% getting the output of the code
disp(b)
