For example a sort of ginput command. Here we discuss the basic syntax of ginput and we also see different examples of input in detail. Make sure that the pointersymbol is set to [] if nargin==1. Is it possible to wait for the user to click a point then store the X coordinate (or index) of this point to a variable within my code? MATLAB is a computing platform that is used for engineering and scientific applications like data analysis, signal and image processing, control systems, wireless communications, and robotics. The Figure must have focus before ginput receives input. Then I want to pick, with ginput, EXACTLY, some of the data on the graph. MATLAB (Matrix Laboratory) [18] is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. I use ginput (1) twice. [X,Y] = GINPUT (N) gets N points from the graph window and returns the X- and Y-coordinates in length N vectors X and Y. Jan 4, 2026 · This guide provides a practical walkthrough for first-time users to reconstruct a 3D model from a single photograph using the single-view metrology system. May 13, 2014 · Matlab has the ginput for getting the (x,y) value of where you have clicked on the graph. This MATLAB function allows you to identify the coordinates of n points within Cartesian, polar, or geographic axes. Jul 12, 2023 · You can try smoothing the plot using maybe gaussian smoothing and then use the smoothed values to determine the local minimums. Mar 6, 2023 · Guide to Matlab ginput. Find project ideas, courseware, and tools to enhance your curriculum. I cannot seem to get my image to display the coordinates of my mouse cursor, and also use ginput to store points at the same time. Learn core MATLAB functionality for data analysis, modeling, and programming. e. This Video will show you how to use ginput command to get the coordinates of any point on a plot in Matlab. MATLAB is a computing platform that is used for engineering and scientific applications like data analysis, signal and image processing, control systems, wireless communications, and robotics. Discover dynamic system modeling, model hierarchy, and component reusability in this comprehensive introduction to Simulink. The cross-hair can be positioned using a mouse (or by using the Arrow Keys on a terminal). That would cause only heel strikes to appear. I currently am trying the following: ginput enables you to select points from the figure using the mouse or arrow keys for cursor positioning. However, say that I have plotted a graph with plot (t, sin (2*pi*t)). Is it possible? How can be done? This MATLAB function allows you to identify the coordinates of n points within Cartesian, polar, or geographic axes. Alternatively, you could parse the mouse input pixel from the graph (see documentation for ginput) and search the closest heel strike point to it in another MATLAB script. When the user clicks on an axes to select a point, ginput makes it the current axes, which makes drawing the point easier. Log in to use MATLAB online in your browser or download MATLAB on your computer. Sep 17, 2025 · MATLAB ( MATrix LABoratory) is a programming and numeric computing platform developed by MathWorks. [x,y] = ginput(n) enables you to select n points from the current Axes and returns the x - and y -coordinates in the column vectors x and y, respectively. It is widely used by engineers, scientists and researchers for solving mathematical problems, analyzing data, developing algorithms and creating models. m which has precedence in your Matlab path. Adapt this copy to take two arguments: "Number of ginput points" and "pointersymbol". Jun 27, 2009 · Why does using "ginput" on 3D surfaces not return the correct point of contact? If I use "ginput" on a 3D plot, such as a surface, the coordinates returned are not the coordinates where the mouse Jan 17, 2014 · For example, you can use [x,y] = ginput (2) to let the user get 2 points before displaying them. Description ginput enables you to select points from the Figure using the mouse or arrow keys for cursor positioning. You can connect to cloud storage solutions and collaborate on projects through a web browser without installing software. Nov 6, 2025 · MATLAB combines a desktop environment tuned for iterative analysis and design processes with a programming language that expresses matrix and array mathematics directly. having a red dot over the area where I clicked so that I later am a Oct 25, 2019 · I plot a line with experimental data (x,y). MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Data points are entered by pressing a mouse button or any key on the keyboard. I want to be able to have the cursor mo Jun 23, 2020 · I am using ginput to select a location within a plot. . The figure must have focus before ginput receives input. Millions of engineers and scientists worldwide use MATLAB to analyze and design the systems and products transforming our world. It focuses on the hands-on execution of the Jul 25, 2011 · Hi Community, I was wondering if it were possible to be able to know where one clicked on an image while using ginput(n), i. However, I prefer drawing the point selected by the user right after a click. Jul 8, 2014 · In MATLAB, I can select a data point using the Data Cursor tool and it will display the X and Y of that point (see figure below). MATLAB Online extends the capabilities of MATLAB and Simulink to the cloud. This MATLAB function allows you to identify the coordinates of n points within Cartesian, polar, or geographic axes. You can get the latest software release, access your campus or corporate license, get a trial, use MATLAB Online, or request a quote to purchase MATLAB for your organization.
