MATLAB: How to plot a for loop

for looplooploopsMATLABplotplotting

Hey guys, I'm having difficulty plotting this for loop. It keeps only giving me x values of -2 to 4 on the graph, but I need it to plot from -2 to 6
%% Problem 1.2
clc, clear all
e=2.718;
x=-2:6;
for k1=1:length(x)
    if x(k1)<-1
        y(k1)=e.^(x(k1)+1)
    elseif x(k1)>=-1 && x(k1)<5
        y(k1)=2+cos(pi.*x(k1))
    elseif x>=5
        y(k1)=10.*(x(k1)-5)+1
    else
        fprintf('\nanswer not given\n')
        y(k1)=NaN
    end
end
plot(x,y)

Best Answer

change
   elseif x>=5
to
   elseif x(k1)>=5
