@Harshil trplot is not the default MATLAB function it is part of Robotics Toolbox. see 'Robotics Toolbox - Peter Corke'
If you're seeing the "Unrecognized function or variable 'trplot'" error, it most likely means that the Robotics Toolbox is not installed or not properly added to MATLAB's path. Here's what you can do:
Install the Robotics Toolbox: If you haven't installed the Robotics Toolbox, you'll need to do so. You can find it on the official MathWorks File Exchange site or sometimes directly through the MATLAB Add-Ons Explorer.
Add to Path: If you've installed the toolbox but are still getting the error, make sure the toolbox's folder is on MATLAB's path. You can add it using the addpath function, like this:
addpath('path_to_toolbox');
Replace 'path_to_toolbox' with the actual path to the Robotics Toolbox directory.
Check for the Function: After installation and adding it to the path, you can confirm the availability of the function by typing:matlabCopy codewhich trplot This will show you the path to the trplot function if it's recognized.
Restart MATLAB: Sometimes, after installing new toolboxes or functions, a restart of MATLAB is necessary for the changes to take effect.
