TaoSetSeparableObjectiveWeights

Give weights for the separable objective values. A vector can be used if only diagonal terms are used, otherwise a matrix can be give. If this function is not used, or if sigma_v and sigma_w are both NULL, then the default identity matrix will be used for weights.

Input Parameters

	tao	- the Tao context
	sigma_v	- vector of weights (diagonal terms only)
	n	- the number of weights (if using off-diagonal)
	rows	- index list of rows for sigma_w
	cols	- index list of columns for sigma_w
	vals	- array of weights

Note: Either sigma_v or sigma_w (or both) should be NULL
