hi i have two vectors diffrent lengths with diffrent values
i want to match closest index in one vector to other
example :
v1 =
[1610759986514 1610759986549 1610759986583 1610759986618 ]
v2= [ 1610759986540 1610759986589]
so result should be in vector 1 match index 2,3 to v2 index 1,2 (time is close enough)

Ran in:
format long g
v1 = [1610759986514 1610759986549 1610759986583 1610759986618 ]
v1 = 1×4
1610759986514 1610759986549 1610759986583 1610759986618
v2 = [1610759986540 1610759986589]
v2 = 1×2
1610759986540 1610759986589
interp1(v1, 1:length(v1), v2, 'nearest', 'extrap')
ans = 1×2
2 3
interp1(v2, 1:length(v2), v1, 'nearest', 'extrap')
ans = 1×4
1 1 2 2
