I'm a uni student and having a bit of trouble with a homework question in an engineering "Optimisation" class. I have a matrix $N$, where they ask you to find the eigenvalues and eigenvectors, which I have done.
Then they ask for you to plot the eigenvalue ($\lambda$), the eigenvector ($z$) and then $\lambda * z$ on an Argand diagram.
I know how to plot the eigenvalue, but am having trouble with plotting the eigenvector (being a $2 \times 1$ matrix).
Say the eigenvector is $[(2 + 3i)/5 \, , 1]^{T}$, how would I plot this on an Argand diagram? What does it even mean to plot a matrix on an Argand diagram? Sorry for my lack of formatting, I am not very familiar with LaTeX. Thanks for any help you can provide! :)
