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 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[*,0] = $#a, $#c[*,1] = $#b[*,0], $#c[*,2] = $#b[*,1], $#c[*,3] = $#a
vmcol
| vmcol(x1M, x2M,...) | Create a matrix using the matrices x1M, x2M,... (the matrices must have the same number of rows as arguments). |
| vmcol(x1V, x2V,...) | Create a matrix using the vectors x1v, x2v, .. (vectors with the same length) - one vector per column.The result is: a matrix (the number of vector elements * the number of vectors) |
