function [edges,nodes,path]=PRM(obstacles)
This is my function.I have a csv file named obstacles.But when I run it, I get the message as Undefined variable "obstacles" or class "obstacles.csv".

I'm afraid the answer is: learn matlab. Function inputs are variables. Matlab is not going to magically guess that a particular variable should suddenly get its content from a file that has (parts) of its name identical to a variable name.
Now, you could create your function where the input variable contains the name of the file to load:
function [edges, nodes, path] = PRM(obstaclefilename)
which you script could call with:
folder = 'C:\somewhere\somefolder';
filename = 'obstacle.csv';
[edges, nodes, path] = PRM(fullfile(folder, filename));
The body of the function could start with:
function [edges, nodes, path] = PRM(obstaclefilename)
filecontent = readtable(obstaclefilename); %use readtable or some other file import function
%... rest of the code that uses filecontent
end

He's obviously trying to learn matlab. The attitude isn't necessary

Function is not linked with obstacles file. Try to create this file again spell should be same.

@Shahid, what does linking a function with a file mean? Your answer makes no sense.
