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)])发布者：全栈程序员-用户IM，转载请注明出处：https://javaforall.cn/119595.html原文链接：https://javaforall.cn
