該樓層疑似違規已被系統折疊?隱藏此樓查看此樓

程序如下：

T=1978:1:2012;

t1=1978:1:2012;

五階擬合函數是f5=0.0049664*T^5-49.4903*T^4+197266.7483*T^3-393146782.4823*T^2+391762509341.9921*T-156152262895446.5;

dc1=diff(0.0049664*T^5-49.4903*T^4+197266.7483*T^3-393146782.4823*T^2+391762509341.9921*T-156152262895446.5) %求導

dc2=(388*t1.^4)/15625-(6965140519951689*t1.^3)/35184372088832+(20334101580882327*t1.^2)/34359738368-(6595908489410563*t1)/8388608+6418636953059199/16384

%離散化

運行結果是：

dc1 =

(388*T^4)/15625 - (6965140519951689*T^3)/35184372088832 + (20334101580882327*T^2)/34359738368 - (6595908489410563*T)/8388608 + 6418636953059199/16384
