Automaticly generate plots and different legend

Hi,

let k is variable. For example, if k=3, then I will have speed1 speed2 speed3.

How can I automaticly generate one plot with all speeds and also different legend for each one?

Thanks

ps:t=0:0.01:100

t=0:0.01:100
speed1=cos(0.01*t);
speed2=sin(0.05*t);
speed3=cos(0.1*t);
y=[speed1;speed2;speed3];
plot(t',y');
for k=1:size(y,1)
  leg{k}=sprintf('speed%d',k);
end
legend(leg);

Hi, but how can I automaticly generate matrix y? I tried

y=[strcat('speed',num2str((1:k)'))];

but it doesnt work. Count of speeds is always different.

How are you generating spped1 speed2 ...

[john]

Now, I wrote it only manual like you

 speed1=sin(a*t);
speed2=sin(a*t);
speed3=sin(a*t);

Where

   for i=1:k;
a=result(i,1);
 end;

Can you help me, how automaticly generate speeds and also matrix y for plot?

Maybe this is part of the solution:

   for i=1:k;
a=result(i,1);
speed(:,i)=sin(a*t);
end;

close
t=0:0.01:100
result=[0.01 0.1 1]
for k=1:3;
  a=result(k);
  speed(:,k)=sin(a*t)';
  leg{k}=sprintf('speed%d',k);
end;
plot(t',speed);
legend(leg);

great....thank a lot ...I also generated acceleration with leg2...in the future, in guide, I would like to add check boxes. Count of check boxes will be based on number k, with possibility to show only checked speeds...it will be difficult?

[john]

Hi, color for leg1 is blue, green, red and color for leg2 is again blue, green, red. I need generate different legends, so there is not possible to repeat any color. Can you help me please?

This is my code

for k=1:3;
             leg1{k}=sprintf('speed_%d',k);
             leg2{k}=sprintf('acceleration_%d',k);
         end
    legend = legend([leg1,leg2]);
