# Matrices and mpmath

Hello, I'm trying to work with matrices. I type `matrix(4)`

and it gives me a 4 by 4 matrix of zeros
which is fine. But when I use the command `from mpmath import *`

then try to create matrices with the same command (`matrix(4)`

) it gives an error message as below:

```
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

raise TypeError('could not interpret given arguments')
TypeError: could not interpret given arguments
```

Since I need this command (`from mpmath import *`

) for other operations, I have to use it. On the
other hand it disrupts my matrix calculations. Is there anyway which I can have both working together in Sage similar to ipython?

Any help would be appreciated. Thank you.
