Hi Deandra,
If you are reading multiple files and if those read operations are independent, then you can use MATLAB's Parallel Computing Toolbox(PCT) to improve the performance. Using PCT's "parfeval", you should be able to read multiple file simultaneously. If you do have access to PCT, then make sure you meet the minimum requirements to use this MATLAB Product, which can be found in the link below: https://www.mathworks.com/products/availability.html#DM
