The unknown matrix is like this:
> x<-matrix(c("x11","x12","x13","x21","x22","x23","x31","x32","x33"),nrow=3,ncol=3,byrow=TRUE)
> x
[,1] [,2] [,3]
[1,] "x11" "x12" "x13"
[2,] "x21" "x22" "x23"
[3,] "x31" "x32" "x33"
This is my distance matrix.

I don't have any cost function to minimize. My task is to create the "best"
matrix, matching the row sums, the column sums, row sumproducts (with the
rows from another constant matrix) and also column sumproducts - it's a
transportation problem of finding OD matrix corresponding the total tonnag

Dear R users,
I have to find optimal solution of an underdetermined linear system, but
only with positive variables. I tried the function from this post
https://stat.ethz.ch/pipermail/r-help/2007-October/143408.html , but it's
solution includes also negative values.
Thanks in advance.
