bcb568 homework

[Katie Wilkins]

Hello all,

Is everyone free to work on the 568 homework Tuesday night?  I'm able to meet any time after 6 if that works for everyone else.

MBB at 6 sounds great.

I was using the wrong matlab function for matrix inverse. 

I got this output for 2b)

A =

   -0.7000    0.2000    0.5000         0         0

    0.3000   -0.3000         0         0         0

    0.3000    0.5000   -1.0000    0.2000         0

         0    0.7000         0   -1.0000         0

    0.3000    0.5000    0.2000         0   -1.0000

B = 

-1

-1

-1

-1

-1

>> A\B

ans =

  111.1111

  114.4444

  107.7778

   81.1111

  113.1111

these are answers to muA, muNotA, muAG, muAGG, muAGGA. Notice we had to set muAGGA to 0 in the 4th row because expected wait time to get to AGGA when you transition to AGGA should be 0.

Thanks!

[Kejue Jia]

haha nice!! Thanks!

I tried again and got a different result.

277.78
281.11
264.44
197.78
277.78

You have to make sure muAGGA is set to 0 in 4th equation. 

[Ruolin Liu]

The only difference between your matrix and mine, actually, is the first equation. I think the [1,2] and [1,3] should be flipped, say -0.7, 0.5, 0.2,0,0

Oh Good catch Roulin, Yes I got those same numbers now:

  277.7778

  281.1111

  264.4444

  197.7778

  277.7778
