Probability

[GP_10383074]

Hi Guys,

I'm doing assignment related to passenger transit probability which indicates the probability that a passenger chooses to travel from floor ''i'' to the floor ''j''. This is only 4 floor building.

''P_arr'' is an arrival rate on each floor and ''U'' is a dedicated population on each floor.

This is a formula which I have to use.

 And this is my initial matrix from Word for calculation's

Does anyone know how to create a matrix 4x4 like below from vector ''U'' and vector ''P_arr"? 

  This is actual case study from one of journals and there are results for this if this helps a bit

 

 I would be very grateful for help

Hi Greg,

Please attach your Prime Worksheet. That saves us from retyping.

Thanks a lot

Or, as long as you keep the vectors P.arr and U the same size, you can do without the explicit indexing:

and with that  you can:

Note that you cannot assemble it into a single expression, due to the vectorization(s) needed.

Success!

Hi,

I have another quick question related to probability.

 For this calculations I have to use "r" (length of travel in floor length) only from first row (i=0) and vector "U" (population on each floor).

 For some reason I have an error, any advice??

For not just some, but an obvious reason.

Your r[0, j vector contains the values 0 through 14, and you let the summation run up to r[0, j -1 .

The first time, for j=0, that results in r[0, j-1 = -1, while your ORIGIN=0.

You're trying to index the array U at -1, while its index starts at 0, hence the index is illegal.

Success!
