ADDTOA Adds a term to the decomposed A matrices [A] = ADDTOA(SDPMAT, WREF_DD, WREF_QQ, WREF_DQ, MATIDX_DD, MATIDX_QQ, MATIDX_DQ, A, SDPVAR, MAXCLIQUE) Adds a matrix multiplied by a sdp variable to the A matrices. Inputs: SDPMAT : A 2*nbus by 2*nbus matrix. WREF_DD : Matrix with three columns. The first column is a numbering 1:size(Wref_dd,1). The second and third columns indicate the row and column indices of the elements of the matrix sdpmat, with the row of Wref_dd corresponding to the index of matidx_dd. That is, the element of sdpmat located in row Wref_dd(i,1), column Wref_dd(i,2) corresponds to matidx_dd(i). WREF_QQ : Similar to Wref_dd, except for the qq entries of sdpmat. WREF_DQ : Similar to Wref_dd, except for the dq entries of sdpmat. MATIDX_DD : Matrix with three columns. Row i of matidx_dd indicates the location of sdpmat(Wref_dd(i,1), Wref_dd(i,2)). The first column indicates the index of the corresponding matrix. The second and third columns indicate the row and column, respectively, of the corresponding matrix. MATIDX_QQ : Similar to matidx_dd, except corresponding to the qq entries of sdpmat. MATIDX_DQ : Similar to matidx_dd, except corresponding to the dq entries of sdpmat. A : Cell array of decomposed A matrices corresponding to maxclique. SVAR : SDP variable (sdpvar) that will be multiplied by sdpmat and added to the decomposed A matrices. MAXCLIQUE : Cell array of the buses in each maximal clique. Outputs: A : Cell array of decomposed A matrices with addition of svar*sdpmat.
