hi guys, can u tell me a different way to sort table by 2 variable columns which more simple than my method?
I want to sort jointTOS by its X and Z from minimum to maximum but X is the priority.
Here the code :
clear;
clc;
H = 5;
L = 15;
Ns = 2;
Nb = 1;
PortalHeight = H;
Bayspan = L;
NumberStory = Ns;
NumberBay = Nb;
% Variable1
h = [0.8,1.00,1.20,1.40,1.6,1.80];
% Variable2
Lss = [2.00,2.40,2.80,3.20,3.60,4.00];
% Variable3
Nss = [2,3,4];
% Definition
Var1HeightofTrussBeam = h;
Var2LengthSpecialSegment = Lss;
Var3NumberSpecialSegment = Nss;
% % Xbase = zeros(1,length(Totalvariant));
% % Zbase = zeros(1,length(Totalvariant));
% % Xcol = zeros(1,length(Totalvariant));
% % Zcol = zeros(1,length(Totalvariant));
% % Xos = zeros(1,length(Totalvariant));
% % Zos = zeros(1,length(Totalvariant));
% % Xss = zeros(1,length(Totalvariant));
% % Zss = zeros(1,length(Totalvariant));
% % X = zeros(1,length(Totalvariant));
% % Z = zeros(1,length(Totalvariant));
% % jointbase = zeros(1,length(Totalvariant));
% % jointcolumn = zeros(1,length(Totalvariant));
% % jointordinarysegment = zeros(1,length(Totalvariant));
% % jointtopordinarysegment = zeros(1,length(Totalvariant));
% % jointbottomordinarysegment = zeros(1,length(Totalvariant));
% % jointspecialsegment = zeros(1,length(Totalvariant));
% % jointtopspecialsegment = zeros(1,length(Totalvariant));
% % jointbottomspecialsegment = zeros(1,length(Totalvariant));
ijk = 0;
for i = 1:numel(h)
for j = 1:numel(Lss)
for k = 1:numel(Nss)
ijk = ijk+1;
Variantmodel{ijk,:} = table(ijk,h(i),Lss(j),Nss(k),'VariableNames',{'VariantID','Height','Length','Number'});
%% Cooridinate Point Base(base)
Xbase{ijk,:} = L*(0:NumberBay);

%% Column(col)

% replicate [X] to be the same size as [Z] for plotting:

Zcol{ijk,:} = [Zcolumn,Zbotbeam];
%% Cooridinate Point Ordinary Segment (os)
% calculate span length of ordinary segment
Los = (L-Lss(j))/2;
Nos = Los/h(i);
Nos = round(Nos);
los = Los/Nos;
totalspan{ijk,:} = los*Nos*2+Lss(j);
if totalspan{ijk,:} == 15.000
checkspan{ijk,:} = "correct span";
else
checkspan{ijk,:} = "span must be 15m";
end
% top and bottom joint of ordinary segment(os)
XTopOrdinarySegment = reshape([los*(1:Nos),(L/2+Lss(j)/2)+los*(0:Nos-1)].'+L*(0:(NumberBay-1)),1,[]);

end

end
% top ordinary segment (TOS)

end
here the resut that i want :
jointTOSnew{1}
ans = 36x3 table

See the "Sort Rows of Table by Variables" example on the documentation page for the sortrows function.
