How can I find the maximum value and its index in array in MATLAB?

Question

Suppose I have an array, a = [2 5 4 7]. What is the function returning the maximum value and its index?

For example, in my case that function should ret

Answer 1

For a matrix you can use this:

[M,I] = max(A(:))

I is the index of A(:) containing the largest element.

Now, use the ind2sub function to extract the row and column indices of A corresponding to the largest element.

[I_row, I_col] = ind2sub(size(A),I)
