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
18 Jan 2012	ENVI file reader, updated 2/9/2010 Read ENVI raster files. Supports all interleaves, data types (except complex) and byte orders. Author: Ian Howat	A better option is to use MATLAB's multibandread function
18 Jan 2012	ENVI file reader/writer Mini-toolbox for reading and writing ENVI data and header files (including complex). Author: Felix Totir	A better option is to use MATLAB's multibandread function
17 Jan 2012	Inscribed_Rectangle Computer vision functions to locate largest square or rectangle inscribed inside arbitrary shape Author: Jaroslaw Tuszynski	No, in the the problems I was working on the rectangles are always parallel to the edges.

29 Jan 2012	adodb_tools Adodb_tools allow communication with different types of databases through ADO OLEDB component. Author: Jaroslaw Tuszynski	sherer, Pete	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);
