I am writing a python script from which I hope to call the Matlab anovan function. I have attempted a basic test of this feature on file test.txt.
This file is imported as array data. In matlab, the anovan function would be called as follows:
anovan(data(:,1),{data(:,2),data(:,3)})In python, I have attempted to call the function like this:
import matlab.engine eng = matlab.engine.start_matlab() data = np.genfromtxt('test.txt') eng.anovan(matlab.double(data[:,0]),matlab.int8(data[:,1:2]))Unfortunately, this gives the following error:
ValueError: initializer must be a rectangular nested sequenceI can see that there is some issue in passing the last two array columns to the function, but am unsure of the solution. Any suggestions would be appreciated.
I have now worked this out. The issue was in the format of the data passed to the function.
#convert grouping columns to integer lists list1 = data[:,1].tolist() for i in range(0,len(list1)): list1[i] = int(list1[i]) list2 = data[:,2].tolist() for i in range(0,len(list2)): list2[i] = int(list2[i]) #The following command now works eng.anovan(matlab.double(data[:,0].tolist()),[matlab.int8(list1),matlab.int8(list2)])版权声明：本文内容由互联网用户自发贡献，该文观点仅代表作者本人。本站仅提供信息存储空间服务，不拥有所有权，不承担相关法律责任。如发现本站有涉嫌侵权/违法违规的内容， 请联系我们举报，一经查实，本站将立刻删除。
