Someone can explain how can I do that “Define transformation matrix A_reflection_yaxis”
At least I need a good source to understand it.

Hi @droz ,

Could you tell us where to find “Define transformation matrix A_reflection_yaxis” so that we can answer your question.

3

it is a first exercise under second part of the last week’s assignment.

4

But I just want to learn how I can create a reflection of a matrix.

5

I applied what I learned from the course as well as investigated other sources. But I only get an error like
“Wrong matrix A_reflection_yaxis.
Check the element in the row 1, column 1.
Wrong matrix containing eigenvalues in the A_reflection_yaxis_eig object. Check that np.linalg.eig function is applied correctly.
Wrong matrix containing eigenvectors in the A_reflection_yaxis_eig object. Check that np.linalg.eig function is applied correctly.
4 Tests passed
3 Tests failed”

Hi @droz ,

I can’t find what that assignment you are referring to. Please copy and paste the title of that notebook, and which exercise.

C1_W4_Assignment
it is about " Eigenvalues and Eigenvectors"

Hi @droz ,

This forum is for the Deep learning specialization, and your question is related to the Maths for Machine Learning and Data Science. Please move your query to that forum and the community members will respond. Thanks

I thought “Maths for Machine Learning and Data Science” is under the Deep learning specialization. That is why I asked here.
