Can the matrix be displayed in a way other than imagesc, imshow, image or pcolor commands (similar to the plot command)?

displaying a matrix by imagesc,imshow,image or pcolor commands is similar to the following figure(serrated line) :

Can the matrix be displayed as a straight line like the plot command?

the matrix is attached.

at the top of the question I think there is a m.file.

The matrix.m file contains two lines:

BW;
imagesc(BW);

One possibility is to use pgonCorners (which must be Downloaded)

to find the approximate vertices of the triangle. Then you can do

load Image

vertices=fliplr( pgonCorners(BW,3) );

plot( polyshape( vertices ) );

set(gca,'YDir','reverse')

what about the irregular shape or a circle ? is it possible to show them ?

I attached the matrixes.

In order to have built such images, you would have to have had to have the vertices. You can use those to plot, if you don't throw them away.
