read max and min value from every column

[hussey]

Dear qudoe

i am trying to make one programme in labview which challenge me to fight with a time.

here i am attaching my labview code in which i have one data file, which consists 500 columns from that i have to find min value and max value from every column.

i tried my best but it takes 30seconds to find min and max value from every column.

i want to perform this operation within a second.

so can any one suggest me any correction required which can boost my program.

You don't have to open and close the file all the time and also you don't really need a while loop to do this. Check the code attached.

Certainly you can still optimize it to get better performance, I just made a quick draft to show you how simple it is.
