Ways to fix

2

Shape of events shouldn't be >1D.

Code to reproduce the exception:

```  from scipy.signal import vectorstrength
import numpy as np
events = np.array([[.5]])
period = 5.
targ_strength = 1.
targ_phase = .1
strength, phase = vectorstrength(events, period)
```

```---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
<ipython-input-2-baa79e52ad7b> in <module>()  5 targ_strength = 1.  6 targ_phase = .1 ----> 7 strength, phase = vectorstrength(events, period)
/usr/local/lib/python3.7/dist-packages/scipy/signal/signaltools.py in vectorstrength(events, period)  3185 period = np.asarray(period)  3186 if events.ndim > 1: -> 3187 raise ValueError('events cannot have dimensions more than 1')  3188 if period.ndim > 1:  3189 raise ValueError('period cannot have dimensions more than 1')
ValueError: events cannot have dimensions more than 1
```

Fixed:

```  from scipy.signal import vectorstrength
import numpy as np
events = np.array([.5])
period = 5.
targ_strength = 1.
targ_phase = .1
strength, phase = vectorstrength(events, period)
```
