I have a matrix and I want every point to be plotted in a graph resembling a parabolic curve

Hi,

I have a random matrix and I want each point from the matrix to be plotted on a graph resembling a parabolic curve.

I have attached a pdf of this explaining in further detail of what I want to obtain.

Thank you very much for your time and effort.

It's not clear that those numbers mean. I don't know what the rows mean, and I don't know what the columns mean. Plus, some numbers occur 3 or more times. Now because it's a parabola, if the numbers were the y values, you could have them occur twice, not not 3 or more times. And if they are x values, that doesn't work because x values can only occur once (in a parabola).

Thank you for the response. What im trying to do is show on a graph the smallest value from a matrix, then the second smallest then third smallest etc. I thought a parabola curve would show these results best but im not so sure now. Is there some other way i can show this?

Why do some numbers occur 3 times?

sortedValues = sort(values, 'ascend')
plot(sortedValues, 'bo-');

There will be numbers occurring repeatedly. Basically the numbers will be representing the levelised energy cost of a tidal current turbine placed at different locations and speeds. So the values will repeat every now and then. Thank you for the suggestion I will give it a try.

i think this is what i was looking for:

figure; [c,h]=contour(distance); clabel(c,h);
