Discounted Cash Flow Analysis
This program performs two kinds of discounted cash flow analysis: net present value (NPV)
and internal rate of return (IRR). It calculates NPV or IRR for up to 24 groups of cash flows.
The cash flows are stored in the two-column matrix C. Matrix C has one row for each group
of cash flows. In each row of C, the first element is the cash flow amount; the second
element is the number of consecutive cash flows having that amount (the number of flows in
that group). The first element of C must be the amount of the initial investment. The cash
