Compare 1D array to a table and fail for unwanted values

[jimbobaggies]

Hi There, looking for a little bit of help if possible.

I am taking some measurements from my signal analyser and from the resultant measurements separating out the frequency components into a 1D array which seems to be the easiest part... in the 1D array I should always have the main frequency component, but also a number of spurious harmonics, however, I have a list of five harmonics that are acceptable, all others would result in a failure.

So essentially I want to take my 1D array of strings, compare it with my list of acceptable values, and return a fail if anything is outside of the list.

TIA

Nested For Loops... Outer one iterates over each value of your 1D Array and inner one iterates over the array of acceptable values.

Hi Andrew thanks for your response.

vi attached with where I got to...

I've used a for loop with a case structure containing a "search 1D array", this is then returning an array containing  index of elements... so what I want now is if the output array contains a '-1', i.e. one of the input elements did not match, then it results in a fail, is there an easy way to search the array for the -1?

Yes, just do it within your For Loop while you are indexing though... See below. Also, you've already told your For Loop how many times to run by indexing over your 3 element array, you don't need to take the array's size and wire it to N too. That's redundant.

I did it in the following way in the end, but thanks for your help, very much appreciated.
