Chapter 1: Problem 6

Use the MATLAB Help Browser to find out how to create a new directory from within MATLAB. Then, create a new directory called mymewdir under the current directory, Add the new directory to the top of MATLAB's path.

Short Answer

Expert verified
First, open the MATLAB Help Browser and search for "create directory" to find the "mkdir" command. Then, create the "mymewdir" folder using `mkdir('mymewdir')`. Finally, add the new directory to the top of the MATLAB path using `addpath(fullfile(pwd, 'mymewdir'), '-begin')`.

Step by step solution

01

Open the MATLAB Help Browser

First, navigate to and open the MATLAB Help Browser by clicking on the 'Help' button on the MATLAB toolbar or typing 'help' in the Command Window.
02

Search for directory creation help

Once the MATLAB Help Browser is open, use the search bar to search for "create directory" or some variation of related terms. This will provide us with the information we need on how to create a new directory using MATLAB.
03

Find the appropriate command

From the search results in the Help Browser, look for a MATLAB built-in function called "mkdir" which stands for 'make directory'. This is the command we will use to create a new directory.
04

Create the new directory

To create a new directory called "mymewdir" under the current directory, type the following command in MATLAB's Command Window: ```matlab mkdir('mymewdir') ``` This will create the "mymewdir" folder under the current directory.
05

Add the new directory to the top of MATLAB's path

Now that we have created the new directory, we need to add it to the top of MATLAB's path. We can do this using the "addpath" command. Type the following command in the Command Window: ```matlab addpath(fullfile(pwd, 'mymewdir'), '-begin') ``` In this command, 'pwd' is used to get the current directory's path and 'fullfile' is used to create the full path of the new directory by concatenating the current directory path with the new directory name. The '-begin' option tells MATLAB to add the new directory to the top of the search path list. Now, the new directory "mymewdir" has been created under the current directory and added to the top of MATLAB's path.
