I get the following error while trying to call odenumjac.
Requested 35036x35036 (9.1GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause MATLAB to become
unresponsive. See array size limit or preference panel for more information.
Error in odenumjac (line 126)
ydel = y(:,ones(1,ny)) + diag(del);
Error in simulation (line 31)
J = odenumjac(@fun,{0 X0}, f0, joptions);
I changed the `Maximum array size` to 10000 in Preference > workspace.
I still face the same error. The size of my physical memory is 8 GB and I can see that the requested array size is ~9 GB.
I would like to know how this problem can be solved.
