How can I change all Inf elements in an array to a specific value?

[westerman111]

I would like to change all Inf elements in my array to -1. Basically, I am looking for something similar to the range and coerce function, except that I want all values above a certain value to be a specific negative value, rather than go to that value.

I could use a case structure and go through each element in the array, but I am hoping to find something more efficient.Any ideas?

Let's clearify a little bit.  You start by saying all Inf values.  Then you say any values above a certain threshold.  Which is it?

If you are just looking for Inf, then I would use a While Loop with a Search 1D Array to find the Inf value, use Replace Array Subset to change the value in the found index to -1.  Stop the loop when the found index is -1 (not found).

If you want above a certain threshold, then you need a FOR loop to go through each element to check if it is above the threshold and then change the value.

If you go with this option, don't forget to use an In Place Element structure. Sounds like a perfect use case.

You can loop through the array and use the in range and coerce, but only check the "coerced" output, and if True, then Replace array subset with your specific value.

I would do that in this way.

If you want to check the values above a threshold just replace the "equal" with "greater or smaller" functions.

I don't understand this logic. sorry

Personally, I would do something close to this (note: I did not really try to optimise anything)...

Here's a simpler version...

Hi,

How abt this?

Agreed Architect but you didn't show the threshold logic. I would consider Don_Phillips's logic more simpler

Yours didn't have a threshold either.  But I fully agree that Don's is the simplest.  I'm curious what benchmarking would show...
