In each figure I have a variable number of plots. However, in the legend I have all the plots. For instance, in the very first figure, I would want only one plot. How can I adjust this?

clc;

clear all;

a=[1/2,1/3,1/4];

l=-0.1:.05:.1;

p = @(x,a,l) 1/3.*(exp(x.^(a))-1)./(exp(x.^(a))+1) + l;

x=linspace(0,.2,101);

for k2 = 1:length(l)

figure(k2)

for k1 = 1:length(a)

plot(x, p(x,a(k1),l(k2)))

hold all

ar{k1} = sprintf('a = %s',rats(a(k1),3));

end

grid

axis([0 .21 0 .25])

hold off

legend(ar, 'Location','best')

end

You need to check if any p are greater than 0. Those elements < 0 would be not shown since you've set the min y value to 0.

clc;

clear all;

a=[1/2,1/3,1/4];

l=-0.1:.05:.1;

p = @(x,a,l) 1/3.*(exp(x.^(a))-1)./(exp(x.^(a))+1) + l;

x=linspace(0,.2,101);

for k2 = 1:length(l)

figure(k2)

legendCounter = 1;

for k1 = 1:length(a)

pValues = p(x,a(k1),l(k2));

plot(x, pValues)

drawnow;

hold all

if any(pValues >= 0)

ar{legendCounter} = sprintf('a = %s',rats(a(k1),3));

legendCounter = legendCounter + 1;

end

end

grid

axis([0 .21 0 .25])

hold off

legend(ar, 'Location','best')

end

You need to make the colors match for the legend and the plot. It's getting later here so I'll let you do that.
