Hi,I don't understand why this is not right,I am a completely new learner!

T=1; lamda=0.4; gamma=1.2; theta=0.1; x=1:100; t=0.1; U=lamda/(0.5*theta^2+lamda); V0(x)=U.*exp(-gamma.*x)-(1-U).*exp(-(0.5.*theta.^2+lamda).*(T-t)).*exp(-gamma.*x); plot3(V0(x),x)

the error is: Error using plot3 Not enough input arguments.

Answer 1

[Thorsten]

plot3 assumes three arguments. Use plot instead

plot(x, V0)

Answer 2

[Torsten]

T=1; 
lambda=0.4; 
gamma=1.2; 
theta=0.1; 
x=1:100; 
t=0.1; 
U=lambda/(0.5*theta^2+lambda); 
V0=U*exp(-gamma*x)-(1-U)*exp(-lambda/U*(T-t))*exp(-gamma*x); 
plot(x,V0)

Best wishes

Torsten.

Already done, thankyou
