Hello, I am having a hard time figuring this out.
Let's say A is a matrix that projects vectors onto \(\begin{pmatrix}1 \\ 3 \end{pmatrix}\).
What is matrix A?
Any help is appreciated.
Thank you in advance!!!
The projection matrix is
\(\begin{pmatrix} 1/10 & 3/10 \\ 1/30 & 1/10 \end{pmatrix}\)
+579
