Using the MATLAB product, you can solve technical computing problems faster than with traditional programming languages, such as C, C++, and Fortran. BUT, if you explicitly pass a list of variables and you only pass one, then I would consider acceptable to load directly the variable. You can use the LOAD command in a loop to load in all the files. Text files often contains a mix of numeric and text data as well as variable and row names, which is best represented in MATLAB ® as a table. The file name corresponds to the channel name allocated in a logging device. If importdata recognizes the file extension, it calls the MATLAB helper function designed to import the associated file format (such as load for MAT-files or xlsread for spreadsheets). mat over csv with respect to speed, size and access are mentioned in this answer of a Mathworks forum discussion: CSV vs MAT files.
