function all_sxint = main
D=1; %L=0;
Pr=1; R=0.1; Sc=1;
xa=0;xb=6;
Lv = [-2.5:0.025:0];
nLv = length(Lv);
all_sxint = cell(nLv, 1);
S = zeros(nLv, 7);
for i=1:nLv
L = Lv(i);
fODE = @(x,y) [y(2); y(3); y(2)^2-y(3)*y(1)-1; y(5); -3*Pr*y(1)*y(5)/(3+4*R); y(7); -Sc*y(1)*y(7)];

all_sxint{i} = sxint;
S(i,:) = sxint(3,:);
end

end
Assign the output to a variable so that you can examine all of the time points for all of the Lv values afterwards, as you indicate that you need to be able to do that.

Lv = [-2.5:0.025:0]; is in your existing code

sxint(3,:) is not a scalar, but the left hand side S(i,1) is a scalar location.

Yes, Actually I need to validate a previous study with mine but unable. Since they have drawn with all points, I am trying in that way.
