inline

Return a vector or matrix with sum zero corresponding to the specified free input.

This is a linear transform, with no Jacobian.

Template Parameters

T	type of the input, either a vector or a matrix
Lp	unused

Parameters

y	Free vector or matrix
lp	unused

Returns

Zero-sum vector or matrix which is one larger in each dimension

This is a linear transform, with no Jacobian.

Template Parameters

Jacobian	unused
T	type of the input
Lp	unused

Parameters

[in]	y	free vector or matrix
[in,out]	lp	unused

Returns

Zero-sum vector or matrix which is one larger in each dimension
