I want to access an excel file with 500 by 2 matrix and check the connected nodes(bidirectional) in that matrix and the output will be a matrix with 1 represent connection otherwise 0.When I run this code,the error is"Maximum variable size exceeded"

clc;
A = csvread('twitnet');
numnode = max(A(:));
adj = zeros(numnode,numnode);
fromlist = A(:,1);
tolist = A(:,2);
fromtoidx = sub2ind([numnode,numnode], fromlist, tolist);
adj(fromtoidx) = 1;
tofromidx = sub2ind([numnode,numnode], tolist, fromlist);
adj(tofromidx) = 1;

See also i-am-a-beginner-in-matlab-so-could-anyone-please-help-me-to-create-an-adjacency-matrix-based-on-th which seems to be the same question as this.

The values in tolist and fromlist are larger than the length of the input numnode. The file has 1000 rows, but only the first 500 are populated. Then using e.g. the indices 1937235 and 2589158 must fail.
We cannot guess, what you want to achieve based on the failing code only. So please edit the question and add more details.
