'abs'— Sort rows of A by abs(A) when A is real or complex. If a column of A has elements with equal magnitude, then use angle(A) in the interval (-π,π] to break ties.Output Arguments collapse all B— Sorted array column vector | matrix Sorted array, returned as a column vec...
table2array:将表转换为同构数组 table2cell :将表转换为元胞数组 table2struct:将表转换为结构体数组 ④使用表的优势 方便将混合类型的数据存储于单个容器中。可以使用table数据类型来将混合类型的数据和元数据属性(例如变量名称、行名称、说明和变量单位)收集到单个容器中。表适用于列向数据或表格数据,这些数据通常...
