MATLAB: Recursion Limit inside parfor

parforrecursion limit

It seems that resetting recursion limit is ignored inside parfor. I have a recursive program that will exceed the default 500 limit. I can run it without problem using usual for loop. However, if I change it to parfor, I got the error

Caused by:
    Maximum recursion limit of 500 reached. Use
    set(0,'RecursionLimit',N) to change the limit. Be aware
    that exceeding your available stack space can crash MATLAB
    and/or your computer.

And no matter where I put the reset limit command set(0,'RecursionLimit',2000) (inside or outside parfor). I still got the same error message

Best Answer

I would try calling

    spmd
        set(0, 'RecursionLimit', N);
    end

as this will ensure it executes on all workers.

ode45 should be called outside the ODE function. Your actual ode function is this

function dv=Question3(t,v)
% dv/dt=8-4
dv=4;
end

and then you need to call ode45 from a separate script

to=0;
tf=100;
tspan=[to tf];
v0=0;
[t,v]=ode45(@Question3,tspan,v0);
plot(t,v(:,1));
xlabel('Time(s)');
ylabel('Volume(l)');

Your function is called "splinefit" and it calls a function, which is called "splinefit". Most likely you want another name for your function, such that the function SPLINEFIT is not shadowed.

But it is very strange that you try to fit the strings 'energy_keV' and 'total_w_coh' ! I assume you want to use these strings as names of variables. But this far away from beeing valid Matlab syntax. Therefore I strongly recommend to read the Getting Started chapters in the documentation.

Maybe you want this:

pp = splinefit(energy_keV, total_w_coh, 4);
