This is the hyperlink: Liner Discriminant Analysis
I have found the DCT Coeff of normalized iris.
Now my aim is to perform LDA on these DCT coeff to extract the features from the normalized iris.
function [Y, W, lambda] = LDA(X, L)
Here what are the parameters X and L? Its not mentioned in the matlab files.
I am not able to understand how to make this code work.

Hi Ridhima,
As per my understanding, you want to know the input parameters for the "LDA" function.
The "LDA" function takes two input arguments, the first being "X", which is the feature vector, which will be the DCT coefficient in your case, and the second input to the function is "L", which is the target class. The same can be found in the "main.m" file on the file exchange link for the function.
I hope this helps!
