Create a matrix by merging columns of source vectors and/or matrices.
- Usage
vmcol(x1 {, x2 {, .. }})- x1, x2, ..
- source vectors and/or matrices with the same number of rows
- Result
- A matrix with
nrow(x1)rows. The columns of the arguments are merged from left to right. - See also
- vv, vvget, vvset, vvcat, vmrow, vsubn, vsubc
Example:
#a := eval vv(1,2,3,4,5) #b := eval init(5,2,0) #c := eval vmcol($#a, $#b, $#a) // -> $#c is a matrix with 5 rows and 4 columns: // $#c[*,0] = $#a, #c[*,1] = $#b[*,0], $#c[*,2] = $#b[*,1], $#c[*,3] = $#a
