Sorry for the delay. I think plotting might just be prone to crashing on your system: which is certainly a problem but from the conversation it doesn't seem like Symbolic that is crashing.

1. ezplot("sin(x)") is nothing to do with Symbolic pkg. That is Octave's core ezplot.

2. This is Symbolic's ezplot:

3. But the previous command is the same code path as:

If I understood correctly, 1 and 2 crash and 3 works.

Using ezplot("sin(x)"), I get the same error, program crashed.

Then I try this:
syms x
fx = sin(x)
typeinfo (fx)
ezplot (fx)

Now it works perfectly.

Just to make sure it is quite clearly the interaction with the symbolic package, can you try the following code?

Also, what does the following return

im using symbolic 2.2.2

When I load:

syms x
ezplot(sin(x))

And then press ENTER, it appears the Figure1 window without the representation of sin(x). All in white. Finally, Octave crash and I have to restart the program again.
