A=identity_matrix(2)
def f(n):
matrix_plot(n*A)
f(5)
I'm puzzled as the command matrix_plot(5*A) works fine on itself, but it produces no output when it goes inside a subroutine as in the above SageMath code.
I'd appreciate any help with understanding why this is so/resolving this.
PS I have tested this both on Sagecell.sagemath.org and a local installation.
