利用fisher线性判别分析进行数据降维

RAFISHER2CDA Canonical Discriminant Analysis. While RAFisher1 is a procedure
that produces very different functions for classification that are also called
linear discriminant analysis, RAFisher2cda is a dimension-reduction technique
related to principal component analysis and canonical correlation called 
anonical discriminant analysis. It derives the canonical coefficients parallels
that of one-way MANOVA and it finds linear combinations of the quantitative
variables that provide maximal separation between the classes or groups in much
the same way that principal components summarize total variation. The output
produced are the canonical coefficients and the scored canonical variables. The
canonical coefficients are rotated.

fisher.jpg       A magnificient picture showing R.A. Fisher working
                 on its famous mechanical desk calculator called by him
                 'the millionaire' at Whittingehame Lodge in 1952. This
                 picture also appears as the frontispiece of the biography
                 by  his  daughter  Joan Fisher Box ['R.A. Fisher: The Life
                 of a Scientist' [1978, John Wiley & Sons, New York]. A

Usage

1. It is necessary you have defined on Matlab the X - data matrix. Size of
matrix (X) must be n-by-p; n=observations, p-independent variables=columns. 

2. For running this file it is necessary to call the rafisher function as 
rafisher2cda(X,pp,c,alpha). Please see the help rafisher.

3. Once you input the arguments, it will appears your results.
