I am trying to pickout peaks of data density. I fit my data to a kernel density estimation using the mvksdensity function.
I then get a matrix, Z, the size of my grid where the values correspond to the density of the data in the 3D variable space.
My question is, can I use islocalmax2 to pick out peaks in this nxnxn matrix Z, or does it only work in 2 dimensional arrays.
The documentation lists the input data can be a multidimensional array, though I’m not sure if it works with a page size greater than 1.
My goal is to calculate the prominence of of these peaks as well so if anyone has any resources related to that in more than 2 dimensions, that would be very helpful.
I’ve also used the imregional max function from the image processing toolbox, but the user doesn’t have control over any parameters for the peaks.I am trying to pickout peaks of data density. I fit my data to a kernel density estimation using the mvksdensity function.
