Question: Extracting data from a 2D plot to compare in Matlab

Hello;

I would like to extract data from a 2D plot to compare my numerical result in Matlab. 

I used this command.

However, I need to spesify the nodes on x axis to get the error in Matlab. My matlab codes give the result as fix step size i.e [0 0.1 0.2 ... 1.0] or [0 0.01 0.02 ... 1.00] etc.

Is there any command in Maple to spesify the nodes on x axis?

Thanks you!
