Matrix to Series

[luching]

How can I convert a matrix into a series? I tried using %pt, but it seems to work only when the matrix is a column matrix.

What exactly are you trying to do? If you're trying to create series out of a column of a matrix, you can do

Code: Select all

set col1 1 %rows(matrix) = matrix(t,1)
set col2 1 %rows(matrix) = matrix(t,2)

etc.

If you're trying to create a whole collection of series that way, you can do:

Code: Select all

dec vect[series] cols(%cols(matrix))
do i=1,%cols(matrix)
   set col(i) 1 %rows(matrix) = matrix(t,i)
end do i

This is a piece of code I wrote to store a vector "shock" over loops of "ndraws" the counter being "accept"

compute capt=%rows(shock)
declare vect[vect] goodshock(ndraws)
dim goodshock(accept)(capt)
ewise goodshock(accept)(i)=shock(i)

This throws up an error. This must be trivial, but any thoughts? Thanks.

Is shock your series? If so, the problem would be using %rows(shock). If it's defined from 1 to nstep (or something like that), just use capt=nstep.

[luching]

Shock is actually a matrix. So the error is not from %rows. The error message I got is

## SX20. Expected , Here
>>>>ept)(i)=shock(i)<<<<

[TomDoan]

If shock is an Nx1 matrix, you need to use shock(i,1), not just shock(i).

Thanks. I did it this way, it works. I guess the one column matrix in "shock" must be taken as one "element" once I define goodshock as vect[vect]

declare vect[vect] goodshock(nkeep)
compute goodshock(accept+1) =shock
