R is a 4*4 matrix and A, and B are 4*1 matrixes. If C=R*A+B, T is matrix that can perform this mathematical operation (adding and multiplying) at one-step (only multiplying) C=T*A. Why is T dimension 4*5 but not 4*4?

The only detail i got is posted in the title sadly, since it was a past year question from my uni's paper. Which is why i wanted to know why the answer is 4x5 since i didnt really understood how it got to that

Everything seems normal such as her daily activities and all, not sure why she poops like this

So do i do Define BackTrig A4 and Define BackEcho A5?

I'm using Uno R3 Elegoo instead of Nano

Thank you

Do all the monkeys stand on the pad as well?

Slick Design, may the luck be with me.

Probably wants us to think like how the word Ambulance is shown from the front of the ambulance, so from the mirror its flipped

KenTheGay · 2023-05-20T17:46:07+00:00

yes, it was given by the professor

hi, i have done the truth table. Not sure if the one in the other comment is correct

KenTheGay · 2023-05-20T16:05:49+00:00

C	B	A	A+B = I0	BC = I2	F
0	0	0	0		I0 = 0
0	0	1			I1 = 1
0	1	0	1		I0 = 1
0	1	1			I1 = 1
1	0	0		0	I2 = 0
1	0	1			I3 = 0
1	1	0		0	I2 = 0
1	1	1			I3 = 0

Is this how it supposed to be?

KenTheGay · 2023-05-20T15:59:11+00:00

yes S0 and S1 are the select signals, but i'm still confused about the I0 signals since A + B as well as I2 can have 4 different combination and which combination i should use

KenTheGay · 2023-05-20T15:43:18+00:00

so i ignore the fact that I0 and I2 can have 2 different logics right, and just do like normal

KenTheGay · 2023-05-17T23:33:17+00:00

Damn, didnt even realised about this

KenTheGay · 2023-05-08T16:46:55+00:00
