But all the cells in this field are not strings. How to convert their class? If I check their class class(EEG.event(1,4)) I obtain struct. First, I thought to check which cells are not strings:I created a large table (11000x48000) to hold simulations. I want to name each of the columns something descriptive. I was able to get the names I want into a 1x48000 string array, but I believe I have to convert it into a 1x48000 cell array to work. varNames = join ( [repmat ('Sim_',3*1000*16,1), (reshape (repmat (1:1000,3*16,1), [],1)),...This example shows how to convert between text and data types that represent dates and times. The datetime data type represents points in time, such as August 24, 2020, 10:50:30 a.m., and the duration data type represents lengths of time, such as 3 hours, 47 minutes, and 16 seconds. A common reason for converting dates and times to text is to append …
