I am trying to sort the rows in one table (Tright) based on the order in which the rows are present in another table (Tleft)
Tright ->
EndNodes_1 EndNodes_2 var1
__________ __________ _____________
{'1' } {'5' } 4
{'10'} {'3' } 1
{'2' } {'11'} 6
{'2' } {'8' } 2
{'3' } {'14'} 9
Tleft ->
EndNodes_1 EndNodes_2
__________ __________
{'1' } {'5' }
{'2' } {'8'}
{'2' } {'11' }
{'3' } {'14'}
{'10'} {'3' }
Expected output:
T =
EndNodes_1 EndNodes_2 var1
__________ __________ _____________
{'1' } {'5' } 4
{'2' } {'8' } 2
{'2' } {'11'} 6
{'3' } {'14'} 9
{'10'} {'3' } 1
I tried the following,
T = innerjoin(Tleft,Tright)
[~, index] = sort_nat(T.EndNodes_1);
T = T(index,:)
Obtained result:
T ->
EndNodes_1 EndNodes_2 var1
__________ __________ _____________
{'1' } {'5' } 4
{'2' } {'11'} 6
{'2' } {'8' } 2
{'3' } {'14'} 9
{'10'} {'3' } 1
Any suggestions on how to obtain the expected output will be really helpful.
Code:
ar = {'1' '10' '2' '2' '3'};
br = {'5' '3' '11' '8' '14'};
cr = [4 1 6 2 9];
Tright = table(ar',br',cr','VariableNames',{'EndNodes_1','EndNodes_2','var1'})
al = {'1' '2' '2' '3' '10'};
bl = {'5' '8' '11' '14' '3'};
Tleft = table(al',bl','VariableNames',{'EndNodes_1','EndNodes_2'})
T = innerjoin(Tleft,Tright);
[~, index] = sort_nat(T.EndNodes_1);
T = T(index,:)

Hi,
According to my understanding you are trying to arrange the table “Tright” columns in the order of table ‘”Tleft”.
You can use “ismember” to do this as follows:
EndNodes_1 = {'1';'10';'2';'2';'3'};
EndNodes_2 = {'5';'3';'11';'8';'14'};
var1 = [4; 1; 6; 2; 9];
Tright = table(EndNodes_1, EndNodes_2, var1)
t1= table(EndNodes_1, EndNodes_2);
EndNodes_1 = {'1';'2';'2';'3';'10'};
EndNodes_2 = {'5';'8';'11'; '14';'3'};
Tleft = table(EndNodes_1, EndNodes_2)
t2 = Tleft;
[Lt2,Loct1] = ismember(t2, t1, 'rows');
Tright = Tright(Loct1,:)
