[Scilab-users] Scilab control after an impossible calculation

[paul.carrico at free.fr]

thanks for the advice 

well I tried but it does not work as expected ; errcatch seems to be obsolete so I'm testing it with execstr: the warning is not displayed ... why ???? 


########################################### 

mode(0) 


try 
x = 0; 
y = (1/x) 


if execstr(('y','errcatch') <> 0) then 
printf("you''re a fool\n"); 
else 
printf("Everything is going well\n"); 
end 
errclear; 
end

Try errcatch ().

Hi All 

I’m using Scilab as the interface between my optimizer and my finite element solver(s) and sometimes Scilab stops because of unexpected and impossible calculus (1/x with x = 0 as an example ); obviously Scilab stops (and so the optimization). 

I’m wondering if it’s possible: 
- To ask back Scilab a message such as “hey I crashed because you’re a fool and you’ve not anticipated an impossible calculation !!!” 
- To get back Scilab control in order to avoid optimization process crash ? I’ve been thinking in affecting a cost function value at %inf for example (not elegant I recognize) 

I don’t know if I’m understandable enough … 

Paul
