ieInternal2Display

Calculate linear transformation from internal space to display primary space

     T = ieInternal2Display(vci)

 The transformation T finds display values (RGB) that produce the
 internal color space values (e.g., XYZ).  The calculation is performed
 assuming that we have linear control of the display primaries.  To
 create a real display image, we may have to correct for the display
 nonlinearity.

       (displayRGB*displaySPD')*internalCS = internalValues
       displayRGB*(displaySPD'*internalCS) = internalValues
       displayRGB = internalValues * inv(displaySPD'*internalCS);
  So, 
       internal2display = inv(displaySPD'*internalCS);

 Example:  

 Suppose result is in the internal color space (e.g., XYZ)

   img = imageGet(vci,'result');
   T = ieInternal2Display(vci);
   displayImage = imageLinearTransform(img,T);
