data type not understood during attaching some matrix blocks to each other
Here is my attempt to build a big matrix out of some smaller ones:
import numpy as np
lambda1 = 1
lambda3 = 0.03
def create_Lambda_matrix(lambda1, lambda3):
Lambda = np.zeros((6,7))
temp3by3 = 2*np.matrix([[lambda1, lambda3, lambda3],[lambda3, lambda1, lambda3],[lambda3, lambda3, lambda1]])
temp2by2 = 2*np.matrix([[lambda1, lambda3],[lambda3, lambda1]])
Lambda = np.bmat([[temp3by3, np.zeros(3,4)]],
[np.zeros(2,3), temp2by2, np.zeros(2,2)],
[np.zeros(2,5), temp2by2]])
return Lambda
Lambda = create_Lambda_matrix(lambda1, lambda3)
print(Lambda)
But a data type not understood error is returned at the line in which Lambda is about to be generated.

the argument of bmat doesn't make sense. It has too many braces, and the lists included have len 2,3,2. I think this is your issue.

You have a syntax error when you define temp2by2. Use instead:
temp2by2 = 2*np.matrix([[lambda1, lambda3],[lambda3, lambda1]])
However you are likely getting the error when you generate you np.zeros matrices. You have to provide the size of the matrix using an array-like type, as you do in Lambda = np.zeros((6,7))
