# Convert a sage.interfaces.matlab.MatlabElement object

Hi,

I tried the following command to call Matlab to generate a sparse matrix and multiply it with a vector

```
sage: matlab('rand(3)')*matrix([1,2,2]).T
0.0344 0.7655 0.4898
0.4387 0.7952 0.4456
0.3816 0.1869 0.6463
```

This is not correct. It seems the multiplication is not done. I'm curious if there is anyway to do the multiplication of a sage.interfaces.matlab.MatlabElement object and a built-in matrix object? Or is there anyway to convert a sage.interfaces.matlab.MatlabElement object to one that can do multiplications with the built-in matrix types? Thanks

Can you just do `matlab('rand(3)').sage()` to get such a thing? I don't have access to Matlab, but in principle this should work; however, for Matlab it seems to just use a string representation so maybe that wouldn't be enough...

It does not work and complains "NotImplementedError: Unable to parse output", by the way, I'm using sage-5.3
