Algorithm (Workflow)

This function, selectsubplot, is designed to interactively select a subplot within a MATLAB figure. It is part of the SolidGeometry library and was introduced in version 5.0. The function is primarily used for user interface purposes, allowing users to identify and work with specific subplots within a graphical figure.

Input Parameters

The function selectsubplot does not take any input parameters. It operates on the current figure and axes available in the MATLAB environment.

Output Results

• hi: This is the handle to the subplot that was selected by the last click cursor position. It identifies which subplot the user interacted with last.
• cfsp: This is a list of all subplot handles within the current figure. It provides a comprehensive list of all subplot axes present in the figure.
• hk: This is a list of subplot handles that were not selected. It includes all subplot axes except the one identified by hi.

Algorithm Steps

1. The function begins by identifying all objects of type 'Axes' within the current figure using the findobj function. This is stored in the variable cfsp.
2. It then determines which of these axes is the current axes (the one most recently interacted with) using ismember in conjunction with gca (get current axes). The result is stored in hi.
3. The function also identifies all axes that are not the current axes by using the logical negation of the previous step. These are stored in hk.

Example Usage

An example of how to use this function is provided in the comments:

PLsample; ginput(1);
selectsubplot

In this example, PLsample presumably sets up a figure with subplots, and ginput(1) waits for a mouse click to select a subplot. The selectsubplot function is then called to identify the selected subplot.
