 function vect = spacedvector(spacing, nPoints)
     % SPACEDVECTOR Returns a vector based on chosen spacing and number of points
+    %
+    % Spacing:
+    %   - linear     : points spaced linearily
+    %   - halfcosine : more dense at beginning and end of vector
+    %   - cosine     : more dense at the beginning and more spaced out at the end
+    %   - sine       : more dense at the end and more spaced out at the beginning
