COPL = ISCOPLANAR(X,Y,Z,TOLERANCE) takes input arguments x,y, and z as column vectors; TOLERANCE is optional.COPL = ISCOPLANAR(x) takes an n x 3 input argument in the form [x1 y1 z1;x2 y2 z2;...;xn yn zn] The optional argument TOLERANCE allows for roundoff error; if each combination of four points is truly coplanar, the volume of the tetrahedron they define is zero. When computational round-off error is introduced, this volume can be close to, but not equal to zero. Setting the tolerance to a value greater than zero enables the algorithm to return a 'correct' finding of coplanarity within the tolerance specified. EXAMPLES:iscoplanar([1 2 -2;-3 1 -14;-1 2 -6;1 -2 -8],eps)copl = iscoplanar([1 -3 -1 1]',[2 1 2 -2]',[-2 -14 -6 -8]')
