Calculating distance from central point to perimeter of shape engulfing central point.

Hi all, I'm trying to make a code which takes a non-moving graph point and calculates the distance from that point to the nearest perimeter point of a shape surrounding it. The shape may vary in sides and location relative to that central point, but the central point will always be located inside of the shape. English is not my first language, so pardon me if this is unprofessionally written. I will attempt to clarify further if it is needed. Thanks, all.

How is the shape represented? As an image? If so, bwdist() will give you the result directly. You could also do

[i,j]=find(yourImage);

mindist=min( (i-i0).^2 + (j-j0).^2 );

It is shown as an image, so that should work. I'm not very proficient in matlab, would you be able to send a link to teach me how to use that command?
