Scilab Function

sort - decreasing order sorting

Calling Sequence

[s, [k]]=sort(v)
[s, [k]]=sort(v,'r')
[s, [k]]=sort(v,'c')

Parameters

Description

s=sort(v) sorts v in decreasing order. If v is a matrix, sorting is done columnwise, v being seen as the stacked vector v(:) . [s,k]=sort(v) gives in addition the indices of entries of s in v , i.e. v(k(:)) is the vector s .

s=sort(v,'r') sorts the rows of v in decreasing order i.e. each column of s is obtained from each column of v by reordering it in decreasing order. [s,k]=sort(v,'r') returns in addition in each column of k the indices such that v(k(:,i),i)=s(:,i) for each column index i .

s=sort(v,'c') sorts the columns of v in decreasing order i.e. each row of s is obtained from each row of v by reordering it in decreasing order. [s,k]=sort(v,'c') returns in addition in each row of k the indices such that v(i,k(i,:))=s(i,:) for each row index i .

Complex matrices or vectors are sorted w.r.t their magnitude.

y=sort(A) is valid when A is a sparse vector. Column/row sorting is not implemented for sparse matrices.

Examples


[s,p]=sort(rand(1,10));
//p  is a random permutation of 1:10
A=[1,2,5;3,4,2];
[Asorted,q]=sort(A);A(q(:))-Asorted(:)
v=1:10;
sort(v)
sort(v')
sort(v,'r')  //Does nothing for row vectors
sort(v,'c')
