Create/extract 'reverse'-diagonal matrix or off-diagonal elements

revdiag(x,...)
offdiag(x,type=0,...)

revdiag(x,...) <- value
offdiag(x,type=0,...) <- value

Arguments

• x: vector
• ...: additional arguments to lower level functions
• value: For the assignment function the values to put in the diagonal
• type: 0: upper and lower triangular, 1: upper triangular, 2: lower triangular, 3: upper triangular + diagonal, 4: lower triangular + diagonal
