Hello all,

I have a cell array t and T defined for simplicity as the following:

t = {rand(1,10),rand(1,10)};
T = {rand(1,10),rand(1,10)};

I am trying to plot t against T on two different figures, not a single figure. When I used this,

cellfun(@(x,y) plot(x,y), t,T);

They override each other on a single figure. Is there any way to plot them individually on two figures?

Thanks in advance for the help,

Ahmad Gad

CELLFUN is not really useful here, because it increases the complexity. Do this with a loop instead:

t = {rand(1,10),rand(1,10)};
T = {rand(1,10),rand(1,10)};
for k = 1:numel(t)
    FigH = figure;
    AxesH = axes(FigH);
    plot(AxesH, t{k}, T{k})
end

If you have any good reasons to hide the details in cellfun():

cellfun(@(x, y) plot(axes(figure), x, y), t, T)

The loop is nicer.

I've edited the cellfun version.

When doing graphics operations in a cellfun() or arrayfun() or structfun(), make sure to use "hold on" unless you are generating a new axes or figure each time (which Jan's code does do.)
