[Octave-bug-tracker] [bug #41305] error: eigs: error -14 in dneupd

[Pantxo Diribarne]

Follow-up Comment #10, bug #41305 (project octave):

I forgot to say the last reported issue may not be related to the OP's issue
but rather to the random number generation inaccuracy.

Max, can you check that the random sparse matrix is the consistent e.g. using
the following ? 


for it = 136:139 
rand('state',it); 
W = rand(200); 
W(W < 0.9) = 0; 
W(W != 0) = rand(size(W(W != 0))) - 0.5; 
eigs(W,1,'LM'); 
endfor

w1 = W;

rand('state',it); 
W = rand(200); 
W(W < 0.9) = 0; 
W(W != 0) = rand(size(W(W != 0))) - 0.5; 
eigs(W,1,'LM'); 

all (W == w1)
