Hi,
I am trying to make a rectangular shape with inner boundary value set as one and outer boundary value set as zero. Ideally a smoother transition from inner boundary to put boundary would be really helpful for my case. Following figure can explain the problem better:
In my implementation, I am struggling with the corners in particular with a linear transition from inner to outer boundary.
Following line should run the function to reproduce the the results of figure 2:
jQvals(Trow,Tcol,ouc,our,inc,inr,ptAbvCrk,ptBlwCrk,gridElems);
Relevant variable are in the attached mat file.
Looking forward to the feedback.

For example,
A=zeros(100);
A(30:70,30:70)=1;
A=max(0, 1-bwdist(A)/10);
A( abs( conv2(A,ones(3)/9,'same')-1)<=1e-6)=0;
