I have an array A
, e.g.
A = [-79.0732 -82.1919 -85.0432 -87.0406 -90.0102 -92.6745]
and some number x
(e.g. -90
), and I want to find the index of the element in the array that is closest (in absolute value) to x
.
In my example, the element closest element of A
to x
is -90.0102
, i.e. the 5th element of array A
. How can I, in general, compute the index of the element that is nearest to x
?
If x
is the value of interest and A
is the array, run
[~, inearest] = min(abs(A - x));
Then inearest
will contain the index of the element of array A
that is closest to x
(in absolute value).
