Import of multiple .fig files

Hello, I have .fig file I want to import and extract a data from it in MATLAB. This is my code:

open('f1.fig');
h = findobj(gca,'Type','line')
x=get(h,'Xdata')
y=get(h,'Ydata')
Channel_1 = y{2,1};
Channel_2 = y{3,1};

At this step, I have Channel_1 and Channel_2 arrays with data of f1.fig. All is working just fine. Here is the problem: I have multiple .fig files I want to import in order to extract data from each one of them, one by one, and combine the data together into overall arrays. I stacked at the import step. My code is:

number_of_figures = 20;
for n=1:number_of_figures
    open('f%d.fig', n);
    h = findobj(gca,'Type','line')
    x = get(h,'Xdata')
    y = get(h,'Ydata')
    Channel_1 = y{2,1};
    Channel_2 = y{3,1};
    for i=1:2048
        CH1(i+(n-1)*2048) = Channel_1(i); %combining data of all figures into CH1 array
        CH2(i+(n-1)*2048) = Channel_2(i); %combining data of all figures into CH2 array
    end
end

But it gives the error "Error using open. Too many input arguments." I tried %d, %s, %c - same result. Can someone tell me, how can I import these .fig files in a right way? Thanks in advance, Georgiy.

Not sure why you think open takes a format string. You're missing an sprintf:

open(sprintf('f%d.fig', n));

Thanks! It works!
