I am reading a simulation/test output data in a .xlsx file into a matlab table through a datastore variable. The test data contains 450+ variables, each with 20000+ samples (i.e.) 450+ columns and 20000+ rows but all are numbers. I created a datastore on the excel file, modified the selected variables and variable type properties and used read command to read the file into a matlab table, it took about ~5 minutes. When I triedreadtablecommand on the excel file directly, it took about the same time as well. However when I tried reading the file interactively using matlab export dialog, it took less than 30 seconds, so I am wondering if there's any way to achieve the same level of efficiency programmatically?
