MATLAB簡化循環

Question

好吧，所以我正在努力與這一個。下面的代碼適用於我需要的方式，但是，我確信它可以更短，更簡單。我知道我可以使用for循環來縮短它，我只是不知道怎麼做，任何人都可以在正確的方向指向我。謝謝:)

如果它不是明確的形式代碼我想要做的。我想單獨卷積信號和房間脈衝響應一起使用比卷積功能

你可以嘗試使用電池陣列等不同的工藝。這些是所有類型數據的通用容器：

fn = {'a.wav','b.wav','c.wav'} 

for i=1:length(fn) 
    h{i} = wavread(fn{i}) 

    hrir_L{i} = h{i}(:,1); 
    hrir_R{i} = h{i}(:,2); 

    ....
