I can generate a.msh file format file through this code
filename=['lin','.msh'] ;
fid=fopen(filename,'w');
But every time I run it, I will overwrite the previous data. I want to generate a new.msh file in the same path every time I run it.The generated file name is not required. What should I do?

You can use the tempname function to generate a random file name.
You can also use sprintf to compose a file name that includes the date and time.
Alternatively you can use a FEX submission by Stephen to number your files automatically. You can look it up yourself, but I will edit my answer in a bit.
