Direct Linear Transformation for reconstructing 3D from two 2D photographs

We are trying to rescontruct 3D spatial coordinates from two photographs, by using DLT. Getting the transformation matrices for both view points isn't the problem, but getting the spatial coordinates from the two pictures seems very hard 'even with the solve commando'. Does somebody have an idea how we can solve this?
for more information about the method we are using. http://www.springerlink.com/content/pl32311419760523/fulltext.pdf

i use triangulate function in matlab to get 3d 3D spatial coordinates from two photographs by using the example:(Structure From Motion From Two Views) but its not work , the error message is {Error in triangulate (line 10) A =[x1(1,i)*P1(3,:) - P1(1,:);
Error in StructureFromMotionExample (line 153) points3D = triangulate(matchedPoints1, matchedPoints2, camMatrix1, camMatrix2);} please can you helpe me
