scree_plot

Synopsis

Produces a scree plot of the lambdas (source code).

Usage

handles = scree_plot(lambdas)

• lambdas: a vector of lambdas; can be taken from the GradientMaps object.
• handles: a structure containing the handles of the graphics objects.

Description

scree_plot plots the lambdas scaled to a sum of 1. It is a useful tool for identifying the difference in the importance of each eigenvector (i.e. gradient) with higher lambdas being more important in principal component analysis and diffusion embedding, and lower ones more important in Laplacian eigenmaps.

BrainSpace only provides basic figure building functionality. For more information on how to use MATLAB to create publication-ready figures we recommend delving into graphics object properties (e.g. figure, axes, surface).
