Hi,

It appears fminsearch fails to exit properly, and instead calls the function
that is trying to be minimized again but without the arguments. 

Call fminsearch with:

[pm,ssr] = fminsearch(@fssr,pm0,optimset('Display', 'final'),y,x,ymax,xmax);

It iterates through alright, and produces output:

Simplex size 8.2135e-05 <= 1.0000e-04 and step in function value 0.0000e+00 <=
1.0000e-07...quitting

But then immediately after it gives:

error: 'y' undefined near line 6 column 6
error: called from
    fssr at line 6 column 1
    fminsearch at line 105 column 10
    estm_sym_20180507 at line 41 column 13

It appears to me that Stopping Test 3 is met so fminsearch breaks, however it
then calls the function fssr again. I am sure there is no second call to fssr
within the script that is being run.

Thanks
