Hi Jocab,
I understand that you have a 3D matrix where each layer is of size 3x2, and you want to find the minium value within each layer and subsequently the maximum value of these minimum values.Further you want to locate the index of maximum value obtained in the original array.
Here is the code with explanation to achieve the above functionality -
arr3D = randn(3, 2, 5);
% Find the minima in each layer
min_values = min(arr3D, [], [1 2]);
% Find the maxima of the minimas
[max_of_minima, layer_index] = max(min_values, [], 'all', 'linear');
% Find index of the maxima in the maxima layer
[x,y] = find(arr3D(:,:,layer_index) == max_of_minima);
disp('Layer minimas:');
disp(min_values);
disp(['Maxima of layer minimas: ', num2str(max_of_minima)]);
disp(['Index of maxima: ', num2str(x),",",num2str(y),",",num2str(layer_index)]);
Hope this solves your query.
