TF = issortedrows(A)当矩阵 A 的第一列元素按升序排序时,issortedrows 返回逻辑标量 1;否则,返回 0 。当第一列有连续重复元素时,issortedrows 进一步检查下一列是否按升序排序,以此类推。 TF = issortedrows(A,column)当 A 根据向量 column 中指定的列排序时,issortedrows 返回 1,否则返回 0 。 column...
Sort rows of matrix or table collapse all in page Syntax B = sortrows(A) B = sortrows(A,column) B = sortrows(___,direction) B = sortrows(___,Name,Value) [B,index] = sortrows(___) tblB = sortrows(tblA) tblB = sortrows(tblA,'RowNames') ...
@文心快码BaiduComatematlab排序函数sortrows 文心快码BaiduComate MATLAB中的sortrows函数 1. 基本用途 sortrows函数是MATLAB中用于对矩阵的行进行排序的函数。它根据指定的列对矩阵的行进行排序,保持行的相对元素不变。 2. 主要输入参数及其含义 A:待排序的矩阵。 cols(可选):一个向量,表示按照哪些列进行排序。如果...
2 请注意，降序排列issorted将返回0。3 当对数组使用issorted函数时，必须带有第二个参数'rows'，用以检查是否按行升序。4 issorted按行比较数组的过程如图，首先比较第一列，如果有相同再比较第二列...等等。5 下面说排序函数sort.默认对向量使用，排序后向量中元素升序排列。6 如果对数组使用sort,...
Example:issortedrows(tblA,[1 4])first checks if the table rows are in ascending order based on the first variable, then breaks ties by checking if the rows are in ascending order based on the fourth variable. Example:issortedrows(TT,["Time","X"])checks if the row times of a timeta...
Sorted table, returned as a table or timetable with the same variables astblA. Sort index, returned as a column vector. The sort index describes the rearrangement of the rows in the input such thatB = A(index,:). Thesortrowsfunction uses a stable sorting algorithm. So, when the input ...
sort(A,1) sorts the elements in the columns of A. sort(A,2) sorts the elements in the rows of A. sort returns A if dim is greater than ndims(A). dim is not supported when A is a cell array, that is, sort only operates along the first array dimension whose size does not ...
