03 Feb 2012 adodb_tools Adodb_tools allow communication with different types of databases through ADO OLEDB component. Author: Jaroslaw Tuszynski

Reply to Pete:
I was using this script to add a lot (~60k) of records to access DB, and use access as temporary memory storage to get some MATLAB codes to run on machined with 2GB or RAM. I did not notice any "extreme" slowness, but that might be relative.

The error you see might be due to MS access not supporting multiple queries.

18 Jan 2012 ENVI to MATLAB Read ENVI image file to MATLAB array. Author: Vincent GUISSARD

A better option is to use MATLAB's multibandread function

No, in the the problems I was working on the rectangles are always parallel to the edges.

This is a great script. However it is extremely slow when trying to multiple records to the accessDB. Is there a way to do insert into for multiple records?
Pref.MultipleQuery = true; is not working!
sql = 'INSERT INTO xport (ACCNT,Name) VALUES ("Pers","02")
 INSERT INTO xport (ACCNT,Name) VALUES ("Cars","1008") ';
Got error:
??? Invoke Error, Dispatch Exception:
Source: Microsoft JET Database Engine
Description: Missing semicolon (;) at end of SQL statement.

Error in ==> adodb_query at 54
  ado_recordset = ado_connection.Execute(sql);

Can it find tilted rectangles, not aligned with the image edges?
