Question

a=[2 -2] [-3 4] then find -a2+6a-3i Matrices pls

Answer 1

Step-by-step explanation:

a=[2 -2] [-3 4]

a=2

-a2+6a-3i

=4-12-9

=-17

Answer 2

Answer:

Step-by-step explanation:

In the Matlab example, you have the dot product of the following two vectors A and B and its answer is vector C.

A = [1+i 1-i -1+i -1-i];

B = [3-4i 6-2i 1+2i 4+3i];

Calculate the dot product of A and B.

C = dot(A,B)

C = 1.0000 - 5.0000i

However, when I calculate it, I have vector C = 7  - 17i

That is, I have C vector results as follows below

(1+i) * (3-4i) + (1-i) * (6-2i) + (-1+i) * (1+2i) + (-1-i) * (4+3i) =

(7-i) +( 4-8i) + (-3-i) + (-1-7i) =

7 - 17i.
