I’m using Clustering Pkg and function fuzzy_cmean, and try to assign the cluster number to each data.

If I use `findmax(FuzzyCMeansResult.weights, dims=2)`

will give us (value, CartesianIndex(2)).

Then, I cannot find out how to use `CartesianIndex(2)`

values for real data.

For example, sometimes it will give us:

CartesianIndex(1, 20)

CartesianIndex(2, 19)

…

CartesianIndex(601, 19)

CartesianIndex(602, 11)

I hope to use CartesianIndex(2) 2nd value for candidate cluster for each data.

So, how to convert CartesianIndex values to Int64?
