Hey Friends,
I am trying to plot a vecotr (a solution of deritinal eqution) somting like those:
x(t)=Aexp(-3t)
y(t)=Bexp(2t)
Where A B are contecst ( so i am trying to see serveral function)
thanks a lot, Adam.

You've pretty much got it, but you'll need to define a range of t values, and a value for the constants A, and B. You also need to use the * symbol for multiplication.
t = 0:0.1:10; % a range of t values from 0 to 100, steps of 0.1
A = 1;
B = 2;
x=A*exp(-3*t);
y=B*exp(2*t);
plot(t,x)
hold on
plot(t,y)
legend('x(t)','y(t)')
You may also want to set the vertical scale to log scale:
set(gca,'yscale','log')
