Easy enough to fix the fact that the current number of obs is fewer
than the number of rows in the matrix (and shorten the code a bit):
program drop _all
mata:mata clear
mata:
void function mm_svmat22(string scalar mat, string scalar vlist)
{
st_view(X=., 1::rows(st_matrix(mat)), tokens(vlist))
X[. , .] = st_matrix(mat)
}
end
prog svmat22
syntax anything [,stub(string)]
local vn = cond("`stub'" == "", "var", "`stub'")
qui desc
set obs `=max(r(N), colsof(`anything'))'
forv i=1/`=colsof(`anything')' {
local vname "`vn'`i'"
qui gen double `vname' = .
local vl "`vl' `vname'"
}
mata: mm_svmat22("`anything'","`vl'")
end
// try it out
webuse auto, clear
keep in 1/3
qui corr price mpg headroom trunk weight length
mat corr=r(C)
svmat22 corr
svmat22 corr, stub(sergiy)
