Following the solution to this thread, https://www.mathworks.com/matlabcentral/answers/166188-can-i-call-my-own-custom-matlab-functions-from-python-r2014b I have been able to successfully reach personal MATLAB functions. The issue when calling these functions is that they expect MATLAB column vectors, but Python does not support this, Python uses lists. I tried using Python's numpy to create something that resembles the MATLAB column vector more than a Python list but the matlab.engine doesn't seem to support sending numpy arrays.
How can I send a Python list as a column vector?
Is the only way to have my MATLAB function's take the transpose of the Python list to form a column vector once I have already reached MATLAB?
Below is what I am trying to do.
import matlab.engine
eng = matlab.engine.start_matlab()
eng.addpath(r'c:\myPath', nargout=0)
testList = [0.50, 0.55, 0.60]
transposedTestList = eng.tranpose(testList) # here is where the issue is
output = myMatlabFunction(transposedTestList)

Try MATLAB arrays for Python:
>>> testList=[0.5, 0.55, 0.6]
>>> testVector=matlab.double(testList)
>>> testColumnVector=eng.transpose(testVector)
>>> testVector.size
(1, 3)
>>> testColumnVector.size
(3, 1)
>>> l
