Updating the variable data types to the appropriate MATLAB® data types can benefit your data, based on the type of variables in your file. For example, the first and sixth columns in outages.csv are categorical. By designating these two columns as categorical arrays you can leverage MATLAB functions for processing categorical data. MATLAB can also work with images that you import from other sources. The basic method of importing an image is to use imread (). For example, to import Bar1.jpeg, you type ImportedImage = imread ('Bar1.jpeg'); and press Enter. What you see as output is a matrix that has the same dimensions as the image. If the image has a resolution of 900. Each variable must be a two-dimensional double array. The output includes only the real component of complex numbers. MATLAB writes data from each variable sequentially to the file. If you plan to use the load function to read the file, all variables must have the same number of columns. The load function creates a single variable from the file.
