How to correct the code?

phis=3;phib=8;
cons=-.95:0.5:10;% for plotting
Eg=[-2.9583 5.2519 -6.5456 5.2455 -0.4883 -7.0614];% for 6 prosumers
xi=[1 1 1 1 1 1];
for n=1:1:6
    if Eg(:,n)>=cons
        cons=xi/phis-1;
         elseif Eg(:,n)<cons
        cons=xi/phib-1;
      else
    end
end
plot(cons,'*')
xlabel('No of prosumers')
ylabel('consumption')

I have to plot two dfiiferent values for two condition,But I got the same values for two conditions.Is any there any mistake in the code?

Dimensions of Eg and cons are different....?

you are comparing [Eg(:,n)>=cons] with an array where Eg(:,n) neither greater nor smaller.

see in index 2 of Eg, 5.2519 > 0.5 and 5.2519 < 10. that's why you are getting one single value that is "else" value.

if your variable "cons" and Eg iare same dimension array, then

phis=3;
phib=8;
% cons=-.95:0.5:10;% for plotting
% cons= -8;
cons= [-3,8,-7,6,-2,-8];
Eg=[-2.9583 5.2519 -6.5456 5.2455 -0.4883 -7.0614];% for 6 prosumers
xi=[1 1 1 1 1 1];
C=zeros(1,6);
[idx ]=find(Eg >= cons);
B=xi/phis-1;
B1=B(idx);
[idx2]=find(Eg < cons);
D=xi/phib-1;
D1=D(idx2);
C(idx2)=D1;
C(idx)=B1

C = 1×6

-0.6667 -0.8750 -0.6667 -0.8750 -0.6667 -0.6667

plot(C,'o')
xlabel('No of prosumers')
ylabel('consumption')
