Given two vectors A and B,
I want to find the index of elements of B in A
I tried
A = ["G1", "V2", "G3", "G4", "V1"]
B = ["V1", "G4"];
[sharedvals,idxs] = intersect(A, B, 'stable')
The above returns
idxs =
4
5
Expected result:
idxs =
5
4
Could someone suggest how to obtain the expected result?

idx = arrayfun( @(x)( find(nodes==x) ), subnodes )
works as expected, but I am not sure why the one posted above doesn't works

Ran in:
You muct have thought of this already (as it is one of your tags), but ismember does what you need:
A = ["G1", "V2", "G3", "G4", "V1"];
B = ["V1", "G4"];
[sharedvals,idxs] = ismember(B,A)
sharedvals = 1×2 logical array
1 1
idxs = 1×2
5 4
If you want a column vector you can transpose it.
