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')
d =

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];
>> norm(x-y)
ans =

No. You will have to code it yourself.
There are many different possible meanings for "distance". See

Is therre a way to take in features like a timestamp for evaluation? I would like to get the closest point in time and space.

Write a MATLAB code that calculate the distance between two points X(1,-3,-2) and Y(3,1,2).

It is meaningless to talk about "the" distance between two points, especially when the units of measure are not given.
There are many different distance measures. For example or the Infinity Norm
