Hi Jorge,

I have a somewhat clumsy solution, and i tried it out for only 3 matrices. So its not only ugly, but there may be matters of speed. I tried
mat C = (0,0)
forv i=1/3 { /* in your case, i=1/1200*/
mat C = C\b`i'
}
mat B = C[2...,1...]

Hope this helps.

Chris

Dear Stata listers

I have many matrixes 1x2 (1200 matrixes), but i would like only one matrix (600x2)
In the manual indicates that " \ " mean join row (append matrixes). That is: matrix C=A \ B,
but i have 1200 matrixes!!!!(b1, b2....b1200). How I append this matrixes?

Thanks in advandce

Jorge
