C1_W4 exercise 2 shear x

Confused. I pass the test if I do this (but the plot I get is reflection about y axis not as epected)

Find eigenvalues and eigenvectors or matrix A_reflection_yaxis.

A_shear_x_eig =np.linalg.eig(A_shear_x)

END CODE HERE

However I fail the test if I do this but at the same time I get the lot correct as expected

Find eigenvalues and eigenvectors or matrix A_reflection_yaxis.

A_shear_x_eig =np.linalg.eig(A_reflection_yaxis)

END CODE HERE

There appears to be a typo in the notebook.

The comment text is incorrect:

# Find eigenvalues and eigenvectors or matrix A_reflection_yaxis.
A_shear_x_eig = np.linalg.eig(A_shear_x)

The comment should refer to A_shear_x.
