Interpolating pixels in the Intensity Graph

[altenbach]

First of all, don't put file IO inside a math routine such as my subVI. Do the file IO in a toplevel VI, then send the 2D array to the gears. Keep the code scalable and modular!

Second, you seem to completely misunderstand the function of my VI. It gets data from a 2D array based on fractional indices. You would only get nonzero values if your array would contain at least 162250 rows.

You need to remove the column and row headers to get the intensity data.

You could for example get the fractional indices from the header column/row using "threshold array", then retrieve the interpolated value using my VI. 

Try it!

Sory i checked  other treshold headers and I am not sure understand use treshold with your vi.

Can you check my attachment? Now i can read value but i am not sure is this true 🙂

Thank you.

Try this...

Thank you.

Now i understand threshold function with your example.

Note that a new bilinear interpolation for 2D arrays has been posted here. It performs faster.

hello again

can you tell me altenbach for this bilinear interpolation subvi which mathematical equation did you use ?
