matlab给了我这个错误

？？？错误：文件：Untitled2.m 行：70 列：19 （此处发布的代码的最后一行） 构造“iPeaksK(...end...)”在此上下文中不明确，因为无法确定“iPeaksK”可以是变量的名称，也可以是函数的名称。要使其成为变量，请分配给它；要让它在执行时成为一个函数，请将“end”替换为对所需数组的 LENGTH、SIZE 或 NUMEL 的调用。

你能告诉我错误在哪里吗？非常感谢oyu。

问题似乎是不同大小写的混合，iPeaksK并且iPeaskskend 的使用使 Matlab 误以为 iPeaksK 是一个实际函数。我建议解决两个大写之一并修复所有其他大写。
