In CVXR: Disciplined Convex Optimization
DiagMat R Documentation
Extract Diagonal from a Matrix
Description
Extracts the k-th diagonal of a square matrix as a column vector.
Usage
DiagMat(x, k = 0L, id = NULL)
Arguments
x
A CVXR expression (square matrix).
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 DiagMat expression of shape
c(n - abs(k), 1).
