Re: st: generating a matrix, adding values in a column
Dear Nick and others,
The TRUTH.... I need to send this matrix to someone who is using GAUSS....
that is why I wanted to just generate this matrix and send it across. This
matrix will then be used for simulations.
On the stata manual, i agree... unfortunately i do not have the manuals at
home (only in school) and so could not look it up toute suite today being a
Sunday. Anyway, I will look at them when i am in school tomorrow.
Thanks,
Gauri

1. As with others, I can't believe that you
need this. What do you want to do with it?
However, what I think you are asking for
is just an outer product:
matrix b = J(326,1,1) * (33.12,156,227.8)
2. You can get a sum by using -summarize-
and looking at r(sum) afterwards.
. su area, meanonly
. di r(sum)
At some stage, it is really is more effective
to read systematically and carefully through
the manual and/or a good introductory book
on Stata...

Dear Kit and Phil and Stata list,
I realised that i was not very clear with my question and my sincere
apologies.
I will try and be clear.
1. First of all, both of you are correct. I want to generate the following
input price matrix (not vector) with 326 rows: Input1, Input2 and Input3
are
values that I have calculated elsewhere and would like to insert these to
look like
input1 input2 input3
33.12 156 227.8
33.12 156 227.8
33.12 156 227.8
.
.
.
.
.
until the 326th row.
So I am requesting information on how to generate this matrix.
2. I would like to add the column values from 1 to n(=326). What should I
look for in help to generate this. This is what I would like to do
Plot Area
1 2
2 10
3 5.5
4 22
5 3
Generate Totalarea(a scalar?)=2+10+5.5+22+3=47.5
Again, I am sorry for my imprecise message and thank you for your
responses,
they are nevertheless useful.
