Dear All,

I am having the same problem as Adrian (see his post Nov. 1 2010,
quoted below).

I am getting an error message

no room to add more double literals
r(3000);

while running the following code:

mata mata clear
mata
numeric matrix GetA() {
a=J(792,1,.)
a[1,1]=32
//...skipped...
a[99,1]=100
a[100,1]=56
a[101,1]=56
//...continues....
}

the skipped part contains assignments for each index. There are total
792 assignments in the function - one for each matrix element.

Background: I need to define a large matrix inside my Mata code. I can
do it with assignment element-by-element, direct input or reading from
a file.
I would like to avoid reading from a file.

What is the best way to define, e.g. 100000x1 matrix in the Mata code?
(Another software is writing the Mata program, so I am not concerned
about the amount of labor).

Thank you, Sergiy Radyakin

PS: I couldn't find any reply to his question and also the email from
2007 that he quoted. Sorry if this was already discussed before.
