[Scilab-users] interp and memory

[Antoine Monmayrant]

Hello Jean-Yves,

Yes, you are right, it does look like a memory leak: the memory 
increases linearly with the number of iterations (see attached file and 
modified script below).
But keep in mind that the plot might integrate some growing overhead due 
to the plotting...

mems(1)=mem;
plot(is,mems,'k.');
