- Get cpu result as benchmark, the result files matches the testcases in data.
- Add result compare funtion, you can use '-c' to activate result comparison, also remember to use '-v' to calculate the result vec.

Write this paragraph in the "-c" part in the same way as line 54.

It is more redundant than other character styles.

It is recommended to use the "matrix1024_result.txt" format.

- Please use scientific notation for the values in the res file.
- Regarding precision differences, use the minimum difference in scientific notation or the equal sign.

Replace %f with a higher precision method.
