Greetings all,

`This is probably trivial and overlooking a minor detail, but I have the following code, and I think my problem is that I have to start at zero somewhere:Response_values= 0:0.1:2;phiv=zeros(size(Response_values));for n=1:length(Response_values) if Response_values(n)<2.1 phiv(n)=(4*n)/((4*n.^2+1).^3/2) else phiv(n)=0; endendplot(Response_values,phiv);`

As it is right now, "n" isn't being indexed right, therefore my plot is wrong. I know as of right now it starts at 1 and goes to 21. I wanted the equation to go from 0 to 2 in .1 increments. I know in MATLAB you can't start at an index of zero, so I searched these boards and tried to code the above.

Any help would be appreciated.

Thanks! -J
