Plot symbolic functions for different domain

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

Hi Ameer thank you for reply

it gives me this error:

Error using char

Cell elements must be character arrays.

Error in fplot (line 144)

strArgs = char(args{k});

At which line? What is the complete error message?

[EldaEbrithil]

F has this form:

X has this form:

[Ameer Hamza]

X is a nested cell array. What is inside those cells? If these are limits them try this

fplot(F{i}, X{i}{1})

Oh yes now it works!! Thank you very much Ameer!!
