matlab function issue

[haozi123456]

There seems to be an error in "wAR" function. The parameter 'W' is superfluous in "svmtrain" and will cause error reporting. Only after deleting the 'W' can the program run.

This is the function in weighted libsvm https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/#weights_for_data_instances instead of traditional libsvm.

Hello, Line 23 of the CSPFeature function corresponds to the CSP extraction feature, which should be the eigenvalue and eigenvector of the sum of the two average covariances. What you have calculated here is the inverse matrix of the first type of average covariance multiplied by the eigenvalue and eigenvector of the second type of average covariance. Is this wrong？

Hi, The code is correct. Please see the attached for the formula of CSP. Thanks.

“wAR”函数中似乎存在错误。参数“W”在“svmtrain”中是多余的，将导致错误报告。只有在删除“W”后，程序才能运行。

你好，我在运行程序时也遇到了wAR函数的执行问题。是关于bestC和bestG的，请问这样的问题怎么解决呢？万分期待您的回复！

This is the function in weighted libsvm https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/#weights_for_data_instances instead of the traditional libsvm.

The code says:

%% Uncomment the following if libsvm-weight is not in your path
addpath('D:\Matlab2020a\toolbox\libsvm-weights-3.24\matlab');

Maybe I should make it clearer. Sorry for that.
