For matrices, it is very easy to pass back and forth between sparse and dense representations.
```
sage: M = Matrix([[2,3],[4,5]])
sage: M.is_dense()
True
sage: M.is_sparse()
False
sage: M1 = M.spa…

# Setting the turbine type with a list causes power setpoints to be ignored
I've noticed an issue where if the turbine type is provided via a list, power_setpoints applied will be ignored.

### Steps To Reproduce
_No response_
### Expected Behavior
It is natural to expect that code:
```
R3. = QQ[[]]
print( SR(t) )
```
would print just `t`.
### Actual Behavior
Instead, it prints…

The exponential function accepts a square matrix as an argument , sin and log don't
A matrix can be the argument of any power series
It will converge when all of the eigenvalues are inside the disc …

Here is an example of a bug in constructing a power series with coefficient in an extension of Qp.
```
sage: A = Qp(3,5)
sage: Po. = A[]
sage: f = Po([3,0,-1])
sage: K = f.root_field('a')
sage: a =…
