location of element in matrix
Mostra commenti meno recenti
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.

Do NOT use ismember
Those are floating point values. It would be an extremely bad idea to use ismember on floating point values, because ismember tests for equivalence of the values. Really bad idea:
Those values should be compared using a tolerance, or with ismembertol.
