Example to Linear Discriminant Analysis

Hey User, I have trouble by understanding the Matlab example for the Linear Diskriminant analysis. Matlab is using the example of R. A. Fisher, which is great I think.

But: How could I calculate the discriminant function which we can find in the original paper of R. A. Fisher? In his paper he has calculated the following linear equation:

X = x1+5,9037x2 -7,1299x3 - 10,1036x4

The paper of R.A.Fisher can be find as a pdf here: http://rcs.chph.ras.ru/Tutorials/classification/Fisher.pdf

I'm using the following code in Matlab 2013:

load fisheriris;
obj = ClassificationDiscriminant.fit(meas,species);

The example can be find under the link:

http://www.mathworks.de/de/help/stats/classificationdiscriminantclass.html

Does that function not calculate the coefficient and the discriminant analysis? If somebody could help me, it would be great. Many thanks in advance!

All the best. Grünschnabel

Could anybody help me?!? Thanks a lot!
