Hi rai,

 

I would appreciate it as kind of respect for forum participants if you would clean up your VI before uploading it (or images of its block diagram)…

 

That being said:

- Your inner while loops each run exactly twice. Replace them with FOR loops!

- Lots of unneeded operations, mainly induced by ExpressVI usage. Is there a reason to convert to DDT and immediately convert back to 1D array?

- You already calculate some Min/Max values. Ratio is just a division of two values…

Best regards,
GerdW
