[scilab-Users] using optim function in different versions of Scilab

[Michael BAUDIN]

It seems that there is a bug with the trace function with Scilab 4.1.2.

-->[y1,y2,y3,y4]=prop(u1,u2,u3,u4,ix,iy,sx,sy,dt,A,U,B,PROP,l1);
 !--error 4
undefined variable : trace                  
at line       2 of function fun called by : 
line    12 of function prop called by : 
[y1,y2,y3,y4]=prop(u1,u2,u3,u4,ix,iy,sx,sy,dt,A,U,B,PROP,l1);


The problem is solved for Scilab 5.1.1

Best regards,
