# How can I create a matrix of linestyles for plot to loop through?

So, I have this:
linedex={'-','--','-.',':'};
x=[-2;-3;-4];
for i=1:4
mmm= [0.0803 0.1912 0.1245
0.0239 0.3246 0.1581
0.0164 0.5584 0.2294]; %%%For each loop it gets a different set of values, this is and example one, with the columns being min,max,mean
hold on
plt=plot(x,mmm)
plt.LineStyle(i)=linedex(i);
end
I've also tried plotting them individually, where its the same linedex and loop replacing mmm with three vectors instead.
x=[-2 -3 -4]
min=[0.0803 0.0239 0.0164]
max=[0.1912 0.3246 0.5584]
mean=[0.1245 0.1581 0.2294]
plot(x,min,x,max,x,mean)
but then how would I call to those specific lines, to have them all be one style, while the next set of min,max, and mean are in a new style/and then colors eventually?

You were almost there, you just need to use the right kind of cell array indexing:
C = {'-','--','-.',':'};
x = [-2;-3;-4];
for k = 1:numel(C)
% Simpler:
mmm = k+[0.0803,0.1912,0.1245;0.0239,0.3246,0.1581;0.0164,0.5584,0.2294];
plot(x,mmm,C{k})
% OR alternatively
%plt = plot(x,mmm);
%plt.LineStyle = C{k};
hold on
end
Which produces this:

Exactly what I was trying to do, thank you!

You can use a combination of eval and sprintf. Here I am plotting successive powers of sin(x).
linestyles={'-','--','.-'};
x=linspace(0,90,100);
for i=1:3
eval(sprintf('plot(x,sind(x).^%d,''%s'')',i,cell2mat(linestyles(i))))
hold on
end
Hope this helps!
