BUG: LinearOperator dtype determination broken

5 comment

### Describe your issue. Calling the `LinearOperator` without specifying the dtype activates the dtype determination in ```scipy/sparse/linalg/_interface.py", line 182, in _init_dtype self.dtype = np.asarray(self.matvec(v)).dtype``` that looks strange. In `/scipy/sparse/linalg/_interface.py` the...
