Suppose I have a matrix
A = 3×3
11 13 15
12 14 16
32 18 21
How do I get the output (1,1) (2,1) and (1,3) which indicate the position of the minimum value of each row.

A=[11 13 15
12 14 16
32 18 21];
[minrow,idx] = min(A,[],2) % min value of each row, with column index
result = [(1:size(A,1)).' idx] % 18 is at (3,2) not (1,3)

may be you are looking for this:
A=[11 13 15
12 14 16
32 18 21];
mincol=min(A) % min value of each column
minrow= min(A,[],2) % min value of each row

if you want fine the row,column of minimum of each row, then
A=[11 13 15
12 14 16
32 18 21];
mincol=min(A) % min value of each column
minrow= min(A,[],2) % min value of each row
[row col]=find(ismember(A,minrow))
% here A(1,1)=11 >> A(2,1)=12 >> A(3,2)=18
