Hello all,
I have a Jacobian matrix of 5420-by-5420 which contains symbolic expressions. Then I use matlabFunction to make the Jacobian a function handle. However, it keeps running forever. I don't know if it is freezed/hanged. The sample code is below.
jac=matlabFunction(Jacobian, 'Vars',{[h],[y],[x0],[Pload],[Qload]});
What is the reason that it keeps running? Could anyone please help me regarding this? Thanks in advance.

You are asking it to create more than 25 million elements... it is going to take a while.

Yeah I understand now. matlabFunction roughly does 520 elements per second. So, it's gonna take around 15 hours for 5420*5420 = 29376400 elements. Thank you.
