This example shows how to calculate the duration and modified duration of a cash flow, given a cash flow of nine payments of $2.50 and a final payment $102.50, with a periodic yield of 2.5%.

CashFlow=[2.5 2.5 2.5 2.5 2.5 2.5 2.5 2.5 2.5 102.5];

[Duration, ModDuration] = cfdur(CashFlow, 0.025)
Duration =

    8.9709


ModDuration =

    8.7521
