Extracting numerical data from text file
#Terrain File Terrain.mat #Start Point (xs,ys) -4.8 4.0 From the code above I am trying to extract "-4.8" and save it as xs, and "4.0" saved as ys. I don't know how to tell matlab to look for the "#" that will be at the beginning of every category. this is the project text file code please convert to project.text file for solving. #This is a project file for MAE8 Spring 2014 #Terrain File Terrain.mat #Start Point (xs,ys) -4.8 4.0 #End Point (xe,ye) 4.8 -4.8 #Number of Way Points 2 #Way Points (xwp,ywp) -0.5 4.8 4.7 0.8

If all you need is that start point coordinates, then about the simplest is just
>> [xs ys]=textread('project.txt','%f %f', 1, ...
'headerlines',4,'commentstyle','shell');
>> disp([xs ys])
-4.8000 4.0000
If, otoh, you need the other info as well, then it's essentially the same presuming you'll do a little post-processing--
>> [xs ys]=textread('project.txt','%f %f', ...
'headerlines',4,'commentstyle','shell');
>> disp([xs ys])
-4.8000 4.0000
4.8000 -4.8000
2.0000 0
-0.5000 4.8000
4.7000 0.8000

ix=find(ys(:,2)==0};
