[Setsuna Yuuki.]

A = rand(1,5); %example matrix
[mini,index] = min(A) %mini= minimum value, index =  index of minimum value

or

A = rand(5) %example 5x5 matrix
[minRow,indexRow]=min(A)
[minCol,indexCol]=min(minRow)
index = [indexRow(indexCol) indexCol] %minimum value o 5x5 matrix (row index, column index)

or can use: (https://es.mathworks.com/help/matlab/ref/min.html)

A = rand(5)
[M,I] = min(A(:));
[I_row, I_col] = ind2sub(size(A),I);
index = [I_row I_col]
