indx: Index-finding in a Sorted Vector

In lsei: Solving Least Squares or Quadratic Programming Problems under Equality/Inequality Constraints

Description

For each of given values, indx finds the index of the value in a vector sorted in ascending order that the given value is barely greater than or equal to.

Usage

indx(x, v)

Arguments

x	vector of numeric values, the indices of which are to be found.
v	vector of numeric values sorted in ascending order.

Details

For each x[i], the function returns integer j such that

v[j] <= x[i] < v[j+1]

where v[0] = -Inf and v[n+1] = Inf.

Value

Returns a vector of integers, that are indices of x-values in vector v.
