Hi sam,

 

Hi GerdW, yes monotonously rising number like (15 16 17 23 24 26 26 27),

So you want to check if

x[n] > x[n-1]

?

Just do that!

(The proper check for "monotonously rising" functions would be to compare for ">=", but your example suggest to check just for ">"…)

 

And 2nd yes Linear searching, actually if thousands of rows find then one by one search take time. I need to search data from file for verification. 

I still don't know why you want to use any kind of linear search here…

Best regards,
GerdW

Hi GerdW, for example we get a value of B from another algorithm (let suppose it is 15), now we have 2 knobs in graph (knob A and knob B), we start knob A and knob B both with zero (0) and increment in both knob with 5. Know we check that when both knob value is greater than B. This is current algorithm which i want to change it.

Hi sam,

 

now we have 2 knobs in graph (knob A and knob B),

Why and how do you have "knobs in graphs"?

 

Know we check that when both knob value is greater than B.

Sure! Its a simple comparison with a boolean operation:

IF knobA > B AND knobB > B THEN …

 Is there something you want to show in your image? I don't find anything related to "knob A", "knob B" or "B" in your image…

Best regards,
GerdW

Hi sam,

Yes.

 

if possible then send me link if possible.

Search this forum to find some implementations of a binary search…

i tried to find but i didn't find. For example the values search from xls file take string as a input and display selected string column which is numbers

Hi GerdW, I thanks allot man i done search code, but now i need one more suggestion, currently my code search specific range of data from selected column. For example, if the data in selected columns are like this ( 2 44 7 3 2 6 3 2 6 3 2 6 4 5 2 5 55 66 77 33) and my current code search data from 2 to 6 values. But i need the data  which is monotonously rising at the same time  ( 2 44 7 3 2 6 3 2 6 3 2 6 4 5 2 5 55 66 77 33) like this only these values it can select. For example the range between 2 to 6 are at least 15 times continuously maintain in this range then these values are store in array. Here is my current code VI.

Hi Sam,

 

some thoughts:

When you want to search specific numeric ranges you should operate on numeric values! Why do you operate on string values?

 

But i need the data which is monotonously rising at the same time

Then you need to apply more than just one condition: "InRange AND Rising"…

 

You still don't use AutoCleanup…
