SUMMARY
The C statement sprintf(fname,"%5.5i-%5.5i.%5.5i-%5.5i",1,*nx,1,*ny); formats a string for a filename using specified integer values. The format string %5.5i-%5.5i.%5.5i-%5.5i indicates that each integer will be printed with a width of 5 characters, padded with zeros if necessary, and separated by hyphens and a period. The first and third placeholders are filled with the integer 1, while the second and fourth placeholders are filled with the values pointed to by *nx and *ny, respectively. This results in a structured filename that incorporates matrix dimensions.
