I need to find the distance between two points in the figure, which I have plotted. Is there any function in matlab that could find the distance between two points. Looking for your reply.

You can use the pdist function in the Statistics Toolbox:
e.g: distance between points (0,0) and (2,1)
>> X = [0,0;2,1];
>> d = pdist(X,'euclidean')

in this case you have to have a nested loop so you gaurantee to reach each point int the list

The distance between two points x and y is the same as the magnitude of the vector that points from one point to the other:
>> x = [0 0];
>> y = [2 1];

No. You will have to code it yourself.
There are many different possible meanings for "distance". See http://en.wikipedia.org/wiki/Metric_%28mathematics%29#Examples
Pos=[x1 x2;y1 y2]

if i was to compare one point of a 1d graph and to compare the distances between that point(the reference point) to others on the graph. how can i do that?

I understand you're experiencing doubts over calculating distance between 2 points in the figure for which you have variable values saved in workspace. You can use one of the following methods for your utility:
- norm(): distance between two points as the norm of the difference between the vector elements
- pdist(X): Euclidean distance between pairs of observations in X
- pdist2(X,Y,Distance): distance between each pair of observations in X and Y using the metric specified by Distance.
- distance(): distance between two points in Geographic space
Hope this helps!
