genbinimg: Generating a binary image

In zcebeci/VatAna: Visual Assessment of Clustering Tendency for Finding the Number of Clusters in a Dataset

Description

Generates a binary image matrix having the rectangular blocks through its diagonal.

Usage

genbinimg(nb=10, disp=TRUE, seed=NULL)

Arguments

nb	An integer describes the number of rectangle blocks to be generated on the diagonal of binary image.
disp	A logical value whether generated binary image will be displayed or not. The default value is TRUE.
seed	An integer for reproducibility purpose. The default value is NULL.

Details

This function is used to generate binary images in different structures in order to test the performance of an examined VAT algorithm.

Value

binimg	Matrix for generated binary image.
k	An integer for the number of clusters.
