[scilab-Users] Convergence problem

[Julio Gonzalez-Saenz]

I ran the example on help, and it ran..


x0=0;x1=0:0.1:2*%pi;
X=integrate('sin(x)','x',x0,x1);


Regards,

Julio

I've got the same result ;
integrate('sin(x)','x',0,2.00001*%pi)  -> not converge
integrate('sin(x)','x',0,2.01*%pi)  -> runs but inacurate
integrate('sin(x)','x',0,1.991*%pi)  -> runs but inacurate
x=0:0.001:2*%pi; intsplin(x,sin(x)) -> runs but inacurate

wait for a gurou ?
