what error?

index exceeds matrix dimensions.
error in evalution (line 5)
bintempx(i,[1,2,3,4,5,6,7,8])=parentxy(i,[1,2,3,4,5,6,7,8]);

function [tempx_y_fxy] = evalution(parentxy,fxy)  i=1:6       bintempx(i,[1,2,3,4,5,6,7,8])=parentxy(i,[1,2,3,4,5,6,7,8]);       bintempy(i,[9,10,11,12,13,14,15,16],8)=parentxy(i,[9,10,11,12,13,14,15,16]);      dectempx=bin2dec(bintempx(i,[1,2,3,4,5,6,7,8]));     dectempy=bin2dec(bintempy(i,[9,10,11,12,13,14,15,16]));      tempx_y_fxy(i,1)=dectempx;     tempx_y_fxy(i,2)=dectempy;      tempx_y_fxy(i,3)=fxy(dectempx,dectempy);  end   tempx_y_fxy=sortrows(tempx_y_fxy,3);    end 

bintempx(i,[1,2,3,4,5,6,7,8])=parentxy(i,[1,2,3,4,5,6,7,8]);   %%% ------- 8 doing here??? bintempy(i,[9,10,11,12,13,14,15,16],**8**)=parentxy(i,[9,10,11,12,13,14,15,16]);  dectempx=bin2dec(bintempx(i,[1,2,3,4,5,6,7,8])); dectempy=bin2dec(bintempy(i,[9,10,11,12,13,14,15,16]));  tempx_y_fxy(i,1)=dectempx; tempx_y_fxy(i,2)=dectempy;  tempx_y_fxy(i,3)=fxy(dectempx,dectempy);

change to:

bintempx(i,1:8)=parentxy(i,1:8);   % removed 8, because think typo?? bintempy(i,9:16)=parentxy(i,9:16);  dectempx=bin2dec(bintempx(i,1:8)); dectempy=bin2dec(bintempy(i,9:16));  tempx_y_fxy(i,1)=dectempx; tempx_y_fxy(i,2)=dectempy;  tempx_y_fxy(i,3)=fxy(dectempx,dectempy);

if want select/assign multiple consecutive columns use 1:8 notation example. both should work in opinion second clearer , easier maintain.

and beaker said, check sizes of matrices, matrices use have @ least 6 rows , 16 columns?

i'm having difficult time , hope guys can help. using helicon isapi rewrite version 3.1.0.104 on our iis server. edit http.conf file , have tried , still fail. this trying do: redirect url: https://www.domain.com/switch-by-version?version=2.8.5.2594 to: https://test.domain.com/load/load.aspx?tver=2.8.5.2594 the version number @ end source url change, , need target url have same version number @ end of url example above shows. i tried following not work: rewritecond %{query_string} ^version=(\d\d?)\.(\d\d?)\.(\d\d?)\.(.*)$ [nc] rewriterule ^/switch-by-version(.*)$ https://test.domain.com/load/load.aspx?tver=%1 [r=307,nc,l] any appreciated! thanks. if it's running in equivalent context of .htaccess , rule shouldn't start / . here's simpler version: rewritecond %{query_string} ^version=(\d+\.\d+\.\d+(?:\..+)?)$ [nc] rewriterule ^switch-by-version/?$ https://test.domain.com/load/load.aspx?tver=%1 [r=307,nc,l]

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
