I try to create a matrix with real number. When I try to create one, I get a TypeError message


sage: Z = matrix(2,2)
sage: Z[0,0] = sqrt(2)
TypeError                                 Traceback (most recent call last)
<ipython-input-29-94541bcbfa2b> in <module>()
----> 1 Z[Integer(0),Integer(0)] = sqrt(Integer(2))

TypeError: unable to convert sqrt(2) to an integer

Since I couldn't really find a way to create one in the documentation (at least I didn't find one), I would like to ask, if there is a easy solution to this.

Thank you very much
