How do I dynamically generate a file name for save in MATLAB

I do not know the file name at the time of coding, only at run time.

You're probably trying

fname = 'foobag';
save fname variable;

To do this correctly, you need to use the "functional" form of save:

fname = 'foobar';
save(fname, 'variable');

In fact, it is true in general that the following two lines are equivalent:

command str1 str2 str3
command('str1', 'str2', 'str3')

This allows one replace any or all of the parameters with dynamically generated strings. This is also useful in commands like PRINT, LOAD, CLEAR, etc.

You can use the function form of the SAVE command:

i = 10;
fname = sprintf('myfile%d.mat', i);
save(fname)

How it is possible to save without loop variable? Suppose I took 'x' variable and I want to append at the end of file while saving i.e filex. This show result into file1, file9 somthing like this.
