m = unvech (v, scale) ¶Performs the reverse of vech on the vector v.
Given a Nx1 array v describing the lower triangular part of a
matrix (as obtained from vech), it returns the full matrix.
The upper triangular part of the matrix will be multiplied by scale such that 1 and -1 can be used for symmetric and antisymmetric matrix respectively. scale must be a scalar and defaults to 1.
