calcFX: Calculates the appropriate F(X) value of each observation

Description

Calculate the F(X) of each obseravtion by summing the F(X) of the previous observation with the weight of the current observation, should be used only after the calcWeights has been used on the source matrix

Usage

calcFX(mat)

Arguments

d <- c(1,1,3,4)
e <- c(5,6,7,8)
f <- c(1,1,1,1)
