Error in sym/int

rSym = mupadmex('symobj::intdef',f.s,x.s,a.s,b.s,options);

Integral=int(fun,x,Li,Ls);

[Walter Roberson]

Is fun a symbolic expression or a symbolic function?

Is x a scalar symbolic variable?

Are Li and Ls both scalars? Are they numeric or symbolic ?

Could you save fun, x, Li, Ls to a .mat and attach the .mat for testing ?

Which MATLAB release are you using?
