I have a matrix mat and I want to find location of x in mat matrix.location should be in order of x.
mat =[
1.0000 1.0000 1.0000 1.0000 1.0000 1.0000
0.0099 1.0000 1.0000 0.0120 1.0000 0.0115
0.0093 1.0000 1.0000 0.0120 1.0000 0.0070
1.0000 1.0000 1.0000 1.0000 1.0000 1.0000
0.0098 1.0000 1.0000 0.0089 1.0000 0.0093
1.0000 1.0000 1.0000 1.0000 1.0000 1.0000];
x =[
0.0089
0.0099
0.0070];
A =mat
C=x
numbersInA = unique(C)
numbersInC = unique(C)
for k = 1 : length(numbersInA)
[rowA colA] = find(A==numbersInC(k))
w(k,:)= [rowA , colA]
end
ans is [ 3 6]
[5 4]
[2 1]
but I need this solution::
[5 4]
[2 1]
[3 6]
Thanks in advance.

[l0,ii] = ismembertol(mat(:),x);
[i0,j0] = ind2sub(size(mat),find(l0));
[~,i1] = sort(ii(l0));
out = [i0,j0];
out = out(i1,:);
