Hello,
I am new to matlab and I am stuck with this. If I have a matrix A as follows:
4.4347 4.5156
4.462 4.7074
1.111 .985
I want (2,2) for index and 4.707 for value. I am trying the following:
A = [4.4347 4.5156; 4.462 4.7074;1.111 .985 ]
max(A,[],1,'linear')
and
max(A,[],2,'linear')
But I don'g get the desired answer with either of them. Any help pwuld be greatly appreciated!

A = [4.4347 4.5156; 4.462 4.7074;1.111 .985 ]
A = 3×2
4.4347 4.5156 4.4620 4.7074 1.1110 0.9850
[Amax, idx] = max(A(:))
Amax = 4.7074
idx = 5
[i, j] = ind2sub(size(A), idx)
i = 2
j = 2
