例如在温度监测数据中，[max_temp,idx] = max(temp_data)，发生时间就是time_vector(idx)。某些情况下需要自定义比较规则。比如处理复数数据时，默认按模值比较大小，若需按实部比较，可用real函数预处理数据。对于结构体数组，需用arrayfun配合极值函数，例如max([structArray.value])提取特定字段的极值。

max(a) :"Subscript indices must either be real positive integers or logicals." or realmax(a) / flintmax(a):"Input must be 'single' or 'double'" So how can I get the maximum value? I want 0.009 as answer. Thanks in advanced!
