Hello Guys, i have a two column Matrix, where the first column is the diameter of some particles and the second column is Extiction. So the elements of the second column correspond to those of the first. My question is, is there a function that...
X = sort (Y) is used to sort the elements of Y in the ascending order. If input Y is a vector, the function sort (Y) will sort the elements of the vector Y. If input Y is a matrix, the function sort (Y) will treat the columns as vectors & will sort each column. X = sort...
Create a matrix and sort its rows in ascending order based on the elements in the first column. When the first column contains repeated elements, sortrows looks to the elements in the second column to break the tie. For repeated elements in the second column, sortrows looks to the third col...
若现在需要将矩阵按照行排序,可以任意指定排序比较的列。可以使用sortrows函数。 2、sortrows函数 SORTROWS(X,COL) sorts the matrix based on the columns specified in the vector COL. If an element of COL is positive, the corresponding column in X will be sorted in ascending order; if an element of...
上面的意思是说,在sort函数中,有两个参数,一个参数是dim,dim表示的是按照哪一维排序,如行为1,列为2;第二个参数是mode,mode表示的是按照降序或者升序排列(缺省的时候是升序排列)。 对于矩阵 A=\begin{pmatrix} 5 & 7 & 8 \\ 4 & 6 & 1 \\ 8 & 0 & 7 \end{pmatrix} ...
从上述的结果看出,sort函数会比较矩阵中的每一个元素,将行中的每一个元素或者列中的每一个元素按照升序排列。 若现在需要将矩阵按照行排序,可以任意指定排序比较的列。可以使用sortrows函数。 2、sortrows函数 SORTROWS(X,COL) sorts the matrix based on the columns specified in the ...
[Y,I] = sort(X,DIM,MODE) also returns an index matrix I.IfXisa vector,thenY = X(I).IfXisan m-by-n matrixandDIM=1,thenforj =1:n, Y(:,j) = X(I(:,j),j);endWhenXiscomplex, the elements are sortedbyABS(X). Complex ...

Sort index, returned as a vector, matrix, or multidimensional array.Iis the same size asA. The index vectors are oriented along the same dimension thatsortoperates on. For example, ifAis a 2-by-3 matrix, then[B,I] = sort(A,2)sorts the elements in each row ofA. The outputIis a col...
'auto' — List NaN elements last for ascending order and first for descending order. 'first'— List NaN elements first. 'last'— List NaN elements last. Example: sortx(h,column,'MissingPlacement','last')Output Arguments collapse all C— Sorted color data matrix Sorted color data, returned...
