Add a variable within single quotes

XLfile = dir('*.csv'); %List contents of the current folder
[~, index] = sort(str2double(regexp({XLfile.name},'\d+','match','once')));
XLfile = XLfile(index);
filename =  {XLfile.name};

for k1=1:Num_of_files;
        figure
        plot(x{1,k1}, y{1,k1})
        savefig('filename{1,k1}.fig');
        fig = openfig('filename{1,k1}.fig');
end

Hello everyone,

I am wondering how I insert a variable inside single quotes.

Apparantly, the codes above (not complete codes. I just included essential parts) will not work. But I want to save figures with the n-th filename with extension of fig.

Thank you.

Illustrate with an example of a string and tell exactly at which location the variable have to be inserted!

@madhan ravi you are right! thanks for letting me know. I will definitely do it next time.

I have no idea what your ‘filename’ array is. If it is the name without the ‘.csv’ extension, something like this may work:

savefig(sprintf('%s.fig',filename{1,k1}))

For example:

k1 = 1;
filename{1} = 'My File';
q = sprintf('%s.fig',filename{1,k1})

q =
    'My File.fig'

Experiment to get the result you want.

Thanks! I thought about sprintf, but have not thought about writing a code that way.

As always, my pleasure!
