BVP4c-display iterations while running

Hello,

I am using BVP4c to solve a boundary value problem. I get this error

??? Error using ==> bvp4c at 252 Unable to solve the collocation equations -- a singular Jacobian encountered So,I am trying to find out at each iteration the singularity occurs. Is there anyway to display the iterations in the command window? I will appreciate your help.

Many thanks,

Mona

Pass in a bvp option set with the Stats property set on; see here

You might also want to try setting the SingularTerm option there to see if that overcomes your singularity difficulty.

Walter,

Thanks.

I checked the Stats, but it works when you got the solution. But, in this case that I get the singularity warning, I can not see the Stats.

Do you have any other suggestion?

You could use a global variable in the function that you call; initialize it to 0 before-hand, and increment it by 1 and display the new value each time the function was called.
