Dear Sage community,
Is there a possibility/workaround in Sage to compute the element-wise
multiplication of two matrices? In Matlab there's the .* operator, but
Matlab is useless in my case since I need a symbolic result.
Thanks in advance for every help
Regards,
Lukas
EXAMPLE:
sigma, tau, beta = var('sigma tau beta')
A = matrix([[-1/tau, sigma/tau],[sigma/tau, -1/tau]])
B = matrix([[beta/tau, 0],[0, beta/tau]])
C = matrix([[1,0],[0,1]])
D = matrix([[0,0],[0,0]])
I = identity_matrix(2)
s, t = var('s t')
P = C*(s*I-A)^(-1)*B+D
P = P.simplify_rational()
RGA = P .* P.inverse().transpose()
