Constructs a diagonal matrix from a column vector. If k != 0,
the vector is placed on the k-th super- or sub-diagonal.
Usage
DiagVec(x, k = 0L, id = NULL)
Arguments
- x
A CVXR expression (column vector).
- k
Integer diagonal offset. k = 0 (default) is the main
diagonal, k > 0 is above, k < 0 is below.
- id
Optional integer ID.
Value
A DiagVec expression of shape
c(n + abs(k), n + abs(k)).
