Hi all
i have a cell array where each element F{i} is a symbolic function of the variable x. I would like to plot these functions on their domain. Each domain is contained in a cell array X (due to the fact that each function has a different domain). How can i do that? I have tried with no success:
for i=1:length(F)
figure(1);set(gcf,'Visible', 'on')
plot(X{i},F{i})
xlabel('X')
ylabel('F')
hold on
end
Thank you for the help
Regards

Maybe converting X domain cell arrays to a symbolic array might be the solution
Symbolic_array_domain= cell2sym(X);
but obviously the grouping of each domain is lost

For symbolic variables, use fplot and pass the interval as second input. Try following
for i=1:length(F)
figure(1);set(gcf,'Visible', 'on')
fplot(F{i}, X{i})
xlabel('X')
ylabel('F')
hold on
end
