double() the results of the sub()
Why doesn't 'subs' seem to be working?

Hello, everyone,
I'm currently trying to substitute equilibrium points of a system into the results of a Jacobian matrix in order to evaluate it in these points, but I have some elements of this matrix which are really long (they actually exceed the 25,000 characters of the Command Window, so I try the diary instruction to send them to a .txt file) but I keep on getting a symbolic expression instead of a numeric answer as it is supposed to be. I save these elements but I have a blank file. Does anyone of you know why does this happens? (These elements are really big so I need to have a more realistic value to check the rank of the Jacobian matrix in order to get the system's observability at these equilibrium points - just in case I attached the file of one that I got in symbolic before trying subs)
Thanks a lot
