extract non zero indices from a 1D array

[KevinKM]

Hi all,

I want to extract non zero indices from a 1d array. Can anybody suggest me how to go about it.

Hi kamasani,

can you explain the term "non-zero indices"?

Are you talking about array elements? Do you need non-zero elements?

Use a FOR loop to autoindex your array and a conditional output tunnel:

I have a 1d array of  floating point numbers. I need to extract the index numbers of  non zero floating point numbers.

Hi kamasani,

you want to know the indeces of non-zero elements?

Take my snippet above and do that little change that is needed to get those indices! 🙂

Hi GerdW,

Thanks for your reply, i am using LV2011,i Undestand what you meant. i doubt conditional auto indexing feature is not available in 2011, i need a little more help.

Hi kamasani,

so you need a shift register, a BuildArray node and a case structure.

I'm pretty sure you will find examples for such tasks in the forum…
