C1_W4_Assignment, Exercise 1 - getting error

I’m getting an error on the Exercise 1 of C1_W4_Assignment.
It requires to find A_reflection_yaxis , which corresponds to the reflection about y-axis

Per my understanding, we can find the reflection of a matrix by multiplying the matrix by [[-1,0],[0,1]]
In the current problem, the reflection on y-axis gives →
[[-2,-3], [2,1]]

to get the eigen vectors and the eigen values and eigen values:
we can use → np.linalg.eig(A_reflection_yaxis)

however, when we plot this i’m getting error -

TypeError: Cannot cast array data from dtype('complex128') to dtype('float64') according to the rule 'safe'

what needs to be done to fix this issue ?


I agree with your analysis of what the code should do.

So we’re left with implementation issues.

Please post your code for Exercise 1. I’ll review it, and then delete it to clear the Code of Conduct.
