Question
For a transition matrix for a problem about people migrating from one region to
another,
O the columns will sum to 1 if there are no new people added to the system.
if the number of people increase both rows and columns must sum to more than
1.
O either the rows always sum to 1 or the columns always sum to 1 but not both.
the rows will sum to 1 when the populations increase linearly.
Question 5 ( ,
Find the answer that selects all the true statements about trace.
a) If A = then tr(A) = 16.
%3D
b) If A and
conform for multiplication in either order, then tr(AB)
= tr(BA).
c) If C conforms with A for multiplication CA,
and A and B have the same dimensions, then tr(C(A + B)) = tr(C)tr(A)
+ tr(B)tr(C).
d) If A and B conform for multiplication AB and C have the same dimensions as AB then tr(AB + C
= tr(A)tr(B) + tr(C).
Both c) and d).
