pcatransform.m

这是盲信号的代码 都已经通过编译了 做这方面的同仁可以参考一下 我觉得蛮惯用的

function [finaldata] = PCAtransform(adjusteddata,eigenvectors,dimensions)
% The first two parameters can come from the result of calling PCAprepare on your data.
% The last is up to you.
finaleigs = eigenvectors(:,1:dimensions);
prefinaldata = finaleigs'*adjusteddata';
finaldata = prefinaldata';
