Please in matching values of two similar arrays using a for loop, how do I delete elements that meet the matching criteria for an element in the reference array so its mot matched twice.

I am not certain what you are doing or what your arrays are. However, the ismembertol (link) function is likely the function that will do what you want. Let it do the looping and duplicate checking.

In the documentation discussion on 'DataScale', the ‘A’ and ‘B’ arrays both have 2 columns. It appears that your arguments have different column sizes that that, so a 2-element 'DataScale' vector is not appropriate. Your 'DataScale' value vector has to have the same number of columns as your data. If you want to use 'DataScale' with vectors, use the method in the documentation section on Specify Absolute Tolerance (link).

I still don’t know what you are doing, however investigate the setdiff (link) and intersect (link) functions to see if they will do what you want.

I appreciate your response.

But for the nature of data i have, there are two arrays of 12 columns each. The colums contain particle coordinates and properties.

I intend to match the rows on one array to corresponding rows of the other array, with tolerance value for some of the atributes as conditions for a match.

Please, can i achieve this with ismembertol? or do you know of a better way i can achieve it?

Thanks
