Data must be a single matrix Y or a list of pairs X,Y. Need help on plotting 3D graph!

3 views (last 30 days)
array= Tmax/n; %This expends the data points n = 2000 and Tmax = 20
t = 0:array:Tmax; %This sets the time interval
e = 2.71828; %e's true value
y1 = A0*e.^(-LamdaR.*t).*cos(LamdaI.*t); %This is the position function x(t)
y2 = -A0*LamdaI*e.^(-LamdaR*t).*((sin(LamdaI*t)+((LamdaR/LamdaI))*cos(LamdaI*t)));
%equation above is the speed
%equation (dx/dt)
i am trying to ploy a 3d graph but keep on getting an error that says Data must be a single matrix Y or a list of pairs X,Y. please help?

PetronasAMG: if you need privacy for your questions then you should be hiring a consultant. The MATLAB Answers facility is for volunteers sharing questions and solutions; questions remain on the record so that other people with similar questions can learn from the questions and solutions. We volunteers donate our time to help everyone, for the public good, not for the individual good; lack of privacy is the price you have to pay.
