说明：  这个模型可以在MATLAB中计算资金的贬值情况，根据利率与时间的长度，最后得到资金的现值或终值( For example, the cost of an asset is $13,000 with a life of 10 years. The salvage value of the asset is $1000. To find the remaining depreciable value after 6 years, use the following commands. Find the accumulated depreciation with the straight-line depreciation function, DEPSTLN. )
