Question

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 ...）”在这种情况下是模棱两可的，因为“iPeaksK”无法确定为变量的名称或功能。要使其成为变量，请分配给它;允许它在执行时成为函数，用调用替换“end” 所需阵列上的LENGTH，SIZE或NUMEL。

你可以告诉我哪里出错了吗？非常感谢oyu。

Answer 1

这个问题似乎是不同大写iPeaksK和iPeasksk的混合，并且使用了让Matlab认为iPeaksK是实际功能的结尾。我建议选择两个大写中的一个并修复所有其他大写。

matlab，错误'在这种背景下是模棱两可的'，
