So I tried to solve the matrix above but I couldn't. I decided to see what happened when I pushed it through Numpy (Python): numpy.linalg.linalg.LinAlgError: Singular matrix So I went back to the definition for a singular matrix: A square matrix that is not invertible is called singular or degenerate. The book simply says it is inconsistent.

numpy.matrix.I¶. property. property matrix. I ¶. Returns the (multiplicative) inverse of invertible self.. Parameters None Returns ret matrix object. If self is non-singular, ret is such that ret * self == self * ret == np.matrix(np.eye(self[0,:].size)) all return True.. Raises numpy.linalg.LinAlgError: Singular matrix

The text was updated successfully, but these errors were encountered: Copy link Contributor fscottfoti commented Jun 2 It seems one of iterations by noisyopt.minimizeSPSA is all zero matrix. Then scipy.stats.kde gives LinAlgError: singular matrix.

Any help would greatly be appreciated! If the singular condition still persists, then you have multicollinearity and need to try dropping other variables.

If the determinant of a matrix A is zero, the matrix is called a Singular Matrix and the Inverse of A does not exist. But when I calculate the determinant of A with Wolfram Alpha I get the value det (A) = 0.00001778224561. If I use the command linalg.det (A) in Python, I get the following output: numpy.linalg.LinAlgError¶ exception numpy.linalg.LinAlgError [source] ¶.
