I would like to ask if there is any way to change the datafield type in a shapefile from Matlab R2019a. I manage to handle my data inside Matlab in a field type which is needed (like for example the datetime to be datetime or the float to be float) but after my export in shapefile every field type is converted to text!!!! Any ideas if there is a way to change somehow the dbf file before the export in order to respect my field types?

If you change the data, you need to write into shapefile again using shapewrite to hold the changes.

You can convert the datetime into a number using datenum.
You can also write the date into character:
d = '01/04/2022' ;

the final value will be 20220401 (instead of 01/04/2022) and the filed type: text instead of (Date)
