I am using fimplicit function to plot two implicit curves as follows:



Limit=[ 0 1.5 0 15];
MDensity=1000;
Exactcurve=fimplicit(f,Limit,'MeshDensity',MDensity);
hold on
Aproxcurve=fimplicit(faprox,Limit,'--','MeshDensity',MDensity);


and the output can be seen in the attached figure.
enter image description here



Now I wanna measure the error between the two curves, I tried the following:



RMSE=norm(Aproxcurve.YData-Exactcurve.YData)


But I get error as Aproxcurve.YData and Exactcurve.YData have different dimensions! I am wondering why the outputs of the two implicit curves have different dimensions despite they have the same limit interval and MeshDensity? Even when I remove the limit and the MeshDensity and leave it in the default setting I get the same error.
