Hi,<br>
<br>
Ok, now I remember, it is there :<br>
<br>
<a moz-do-not-send="true"
href="http://forge.scilab.org/index.php/p/number/source/tree/HEAD/macros/number_ismember.sci">http://forge.scilab.org/index.php/p/number/source/tree/HEAD/macros/number_ismember.sci</a><br>
<br>
Unfortunately, I have not released this function in the binary
release yet.<br>
Here is a simplified version:<br>
<br>
function tf = number_ismember ( a , s )<br>
// Array elements that are members of set.<br>
//<br>
// Calling Sequence<br>
// tf = number_ismember ( a , s )<br>
//<br>
// Parameters<br>
// a : a ma-by-na matrix<br>
// s : a 1-by-ns matrix<br>
// tf : a ma-by-na matrix of booleans, tf(i,j) is %t if there
is an entry in s matching a(i,j).<br>
//<br>
// Description<br>
// Search in a the entries which are in s.<br>
// <br>
// Uses vectorized statements, based on the Kronecker product.
<br>
// The intermediate memory required is ma*na*ns.<br>
// <br>
// Examples<br>
// a = (1:5)'<br>
// s = [0 2 4 6 8 10 12 14 16 18 20]<br>
// tf = number_ismember ( a , s )<br>
// expected = [%f %t %f %t %f]'<br>
//<br>
// // An example with a matrix<br>
// a = [<br>
// 7 35 14 86 76 <br>
// 15 51 24 96 49 <br>
// 35 40 46 35 93 <br>
// 85 34 74 82 22<br>
// ];<br>
// s = [51 74 22 15 86] <br>
// tf = number_ismember(a, s)<br>
//<br>
// Authors<br>
// Copyright (C) 2010 - DIGITEO - Michael Baudin<br>
<br>
//<br>
// Check size<br>
// a can have any shape<br>
if ( s==[] ) then<br>
tf=(ones(a)==zeros(a))<br>
return<br>
end<br>
//<br>
// Check content<br>
// Nothing to do.<br>
//<br>
// Proceed...<br>
if ( a==[] ) then<br>
tf=[]<br>
return<br>
end<br>
//<br>
// Convert a into a column vector<br>
ma = size(a,"r")<br>
na = size(a,"c")<br>
a=a(:)<br>
//<br>
ns = size(s,"c")<br>
sp = s .*. ones(na*ma,1)<br>
ap = a .*. ones(1,ns)<br>
tf = or(ap==sp,"c")<br>
//<br>
// Convert tf into the same shape as a<br>
tf=matrix(tf,ma,na)<br>
endfunction<br>
<br>
This is an example:<br>
<br>
--> a = [<br>
--> 7 35 14 86 76 <br>
--> 15 51 24 96 49 <br>
--> 35 40 46 35 93 <br>
--> 85 34 74 82 22<br>
--> ];<br>
<br>
--> s = [51 74 22 15 86] <br>
s =<br>
<br>
51. 74. 22. 15. 86. <br>
<br>
--> tf = number_ismember(a, s)<br>
tf =<br>
