Re: st: moving data to matlab...

[Andrew Shephard <andrew_s@ifs.org.uk>]

I have written a plugin ("matwrite") that is capable of doing exactly 
this. It is available on the ssc archive (type "ssc install matwrite, 
replace" from within stata to install).

matwrite ing[ing*] using "filename"

will export the matrix "ing" that has variables ing* as columns as a 
mat-file called filename. You can export multiple matrices, and can just 
save variables as column vectors also. See the help file for more details.

Please note that you will require Stata 8 and that because it uses a 
compiled plugin, it is platform dependent. If matwrite is not available 
for your platform, I can provide you with the source code if you are 
able to compile it.

Hope you find this useful,

Andrew
