如何在特定范围内累计减法

Question

我该如何调整for循环，以便每次曲线超过最大容量且为负值时（请参见一些示例，如箭头所示），这些值将累计减去容量（请参见黑色曲线） 。使用我的代码，我只能在一点上计算差异，而对实际容量没有影响...您可以在下面找到我的代码。 needed curve

C=cumsum(diffE,'omitnan'); % needed Capacity 
Cbmax= 1000; % in MWH, max. capacity of the battery storage
Cbmin= 100; % in MWh, deep charge border 
imax= C>=Cbmax-Cbmin; % find where C is larger than Cbmax
imin= C<=Cbmin-Cbmin; % find where C is smaller than Cbmin
C(imax) = Cbmax-Cbmin; % if C is larger than Cbmax: C=Cbmax
C(imin) = Cbmin-Cbmin; % if C is smaller than Cbmin: C=Cbmin 
Cres=cumsum(diffE,'omitnan');
for k=1:length(Cres)-1
    if Cres(k)>Cbmax && Cres(k)>Cres(k+1)
           C(k+1)=C(k)-(Cres(k)-Cres(k+1));      
        end
    end  
end
