matlab，錯誤'在這方面是不明確的，'

-2

???錯誤：文件：Untitled2.m行：70列：在這種情況下19 的結構（發佈時間：這裏的代碼的最後一行）「iPeaksK（... ...結束）」是不明確的，因爲「 iPeaksK「不能被確定爲變量的名稱或函數。爲了使其成爲一個變量，分配給它;以允許它在執行時成爲函數，在所需陣列上用長度，大小或NUMEL調用替換「結束」。

請問您能告訴我錯誤在哪裏？非常感謝oyu。

如果您將代碼簡化爲某些展示問題的代碼可能會有所幫助，但這些代碼很少且完全獨立。 – carlosdc

這個問題似乎是不同的資本化iPeaksKiPeasksk和的混合物和最終被混淆Matlab的，以爲iPeaksK是實際功能的使用。我會建議爲兩個大寫字母之一解決並修復所有其他字母。
