%SPROW Extract row of sparse matrix. % X = SPROW(A,J) where A is a sparse matrix, returns the nonzero values in % the row A(J,:). % % [X,ID] = SPROW(A,J) also returns the column indices of the nonzeros. % % Note that the call [X,ID] = SPROW(A,J) is equivalent (but more efficient % than) the Matlab code % % IDS = find(A(J,:)); % X = A(J,IDS); % Ron Rubinstein % Computer Science Department % Technion, Haifa 32000 Israel % ronrubin@cs % % August 2009
