sumvalpr: Sum of a geometric series

Description

Calculates the sum of the first (k+1) terms of a geometric series with initial term 1 and common ratio equal to valpr (lower or equal to 1).

Usage

sumvalpr(k,n,valpr,index1,index0)

Arguments

k
The number of terms minus 1.
n
The length of valpr.
valpr
Vector of common ratio in decreasing order.
index1
The index of the last common ratio equal to 1.
index0
The index of the first common ratio equal to 0.

Value

Returns the vector of the sums of the first (k+1) terms of the geometric series.
