m a row vector
 
  BTKSETPOINTRESIDUALS(H, INDEX, R) uses the matrix R to set point's residuals.
  The number of rows of the matrix corresponds to the number of frames 
  in the acquisition.  The number of columns must be equal to 1.
  The biomechanical acquisition handle H is represented as a double and can
  be only used with the btk* functions.

  BTKSETPOINTRESIDUALS(H, LABEL, R) uses the point's label to extract the point 
  to modify.</pre></div>
