mathematical algorithm

[ravirocks43]

Hello Experts,

I am trying to create a labview VI for mathematical algorithm represented in the attached picture. Please give your suggestions.

Best Regards,

Ravi

Hi ravi,

and what is your problem?

Where are you stuck?

What have you done/tried so far?

Did you forget to attach your VI?

Hi GerdW;

I have made a simple VI for the alogirthm. But I dont know where I use the summation to get all values.Please suggest me  whether I can use a loop for the iteration for summation of values?

Hi Ravi,

there's a "Sum" function in the mathematics palette. Just use it!

How big are your arrays? Do you really need the "MultiCore Sparse Matrix" functions? You have "basic" matrix functions in the Mathematics palette!

Hi GerdW,

I am looking for the correlation of two images to find the displacement in nanometers for the MEMS structure. I have a paper stating the following method for calculation for this purpose. I am attaching the paper for this reason. Please check once and help me if you have more better solution.

Best Regards,

Ravi

Hi Ravi,

just an idea:

This should be correct for u=v=0 (no displacement of G image. Different values of u/v means you need to shift the G array accordingly…

I need to apply convolution instead of multiplication.

Well, although this paper is flawed by the information it omits, it at least makes clear(er) what it is you are trying to do.  You might consider posting a question about "How do I do a correlation of two related images" in the Vision forum ...

there are functions for convolution in the full development suite

maybe they help

Convolution is not the same as Cross-Correlation (Time's Arrow is reversed).
