how does imread know where to look on my computer to find the graphics file?

how does imread know where to look on my computer to find the graphics file? It says file does not exist but it does and is save in a documents folder. In java or html we need to explicitly give the path file to find and read in a file. I have not seen anything that says this for matlab. However matlab can not find my file?? How do I let matlab know where to look?

You can specify the complete path of file with imread()

img = imread('C:\....\imageFile.jpg');

If you don't specify the complete path, then imread() search for the file on MATLAB's path: https://www.mathworks.com/help/matlab/ref/path.html

You can add and remove any folder from MATLAB's path: https://www.mathworks.com/help/matlab/ref/pathtool.html
