Using ismember with some margin

I asked a question yesterday and I got some good answers but there was a twist to my problem want to use a subset of number to find the index in a bigger set, my smaller set has some margin of error +/- 0.001
eg bigger set BS = [2.33, 4.551, 5.88, 3.98, 4.661, 7.98, 2.331, 9.55]
smaller set SS = [4.55 4.66 7.99]
I want to use the smaller set (SS) to pick the index of its location in the bigger set (BS)
I tried using find, ismembertol but not working well
I will be happy to figure this out

Would be better to preserve the history and responses so far to continue your original post with this as a comment, rather than opening up a new question.

ismembertol by default uses relative tolerances. To use absolute tolerance with it you need to set the relative portion to 1 and use one of the named options to set the margin to the absolute value you want.

Sorry details were slightly wrong, see https://www.mathworks.com/help/matlab/ref/ismembertol.html#bup2c1a
