I am using this code to segement a grayscale image and produces an error in activecontour([A, mask, N, method, smoothfactor,contractionbias] = parse_inputs(args{:});
that is the code i use;
I = imread('after opening.jpg');
imshow(I)
r = drawrectangle;
mask = createMask(r);
bw = activecontour(I,mask,200,'edge',1,.3);
hold on;
visboundaries(bw,'Color','r');
figure
imshow(labeloverlay(I,bw));
How could this be solved?

bw = activecontour(I,mask,200,'edge',1,.3);
'edge' is a positional keyword, not a name-value pair. There are no positional values expected after 'edge'. The 1,.3 is unexpected.
It is not clear to me what you were trying to do at that point, but my guess is that you want either
'SmoothFactor', 1, 'ContractionBias', 0.3
or possibly
'SmoothFactor', 1.3
