问题 I have a structure (gilts) in matlab with many fields (gilt_name). The structure is an imported workbook from excel, and each field corresponds to a worksheet in that workbook. Each worksheet is a time series of dates and corresponding prices of gilts. I converted the dates in excel to strings before importing into matlab as instructed in When to Convert Dates from Excel Files. But how do I apply this conversion to many fields simultaneously in matlab? I have hundreds of arrays of data

Here is my implementation on my upload servlet. @SuppressWarnings("serial") public class UploadBlobServlet extends HttpServlet { private static final Logger log = Logger
