WebApr 18, 2024 · You can use a buffer. I mean, suppose the matrix you want is M, then create M=[]; and a vector X=zeros(xsize,2), where xsize is a relatively small value compared with m (the number of rows of M). Then, fill X and when it is filled, just concatenate the matrix with M by doing M=[M; X]; and start filling X again from the first row on. WebA = adjacency (G,'weighted') returns a weighted adjacency matrix, where for each edge (i,j), the value A (i,j) contains the weight of the edge.
