Downloading for Matlab 8.10
A version for 64 bits Matlab 8.10
has been made for Linux, MacOS and Windows 7.
It should also work in Windows 8. The latest
version fixes a bug in calculating fields from
Field II can be slow for certain field points, when
using bounding lines and triangles. This is due to the method employed for
integrating the response. The option set_field('fast_integration',1)
solves this problem, with a very slight reduction in accuracy. I have therefore
chosen to make this option the default method. It can be disabled by writing
set_field('fast_integration',0). Field II version 3.22 has therefore been compiled
for version 8.10 of Matlab for Windows, Mac and Linux.
Note also that for the Windows 64 bits version you have to have
the Microsoft Visual Studio 2012 run-time libraries for this version to work.
This you can either get by installing the compiler and using mex -setup
or download the Microsoft Visual Studio 2012 run-time libraries from the link:
General downloading for Matlab 8.10
The download directory contains a number of compressed tar files. One
for each computer type the program is running under (see below). In each
are located all the files for the release. The tar file can be downloaded
and then expanded to yield all files by using the gzip and tar programs
on UNIX workstations or WinZip on PCs.
The new code on this page will work with Matlab 8.10. Use
the old code version for other version of Matlab. You can find
them under Download in the left menu.
The following operating systems are currently supported:
The tar-file should be downloaded to the directory, that must hold the
files. The file is then extracted by writing:
gzip -d "name_of_tar_file".tar.gz
tar -xvf "name_of_tar_file".tar
to uncompress and extract the files. The tar-file can then be deleted.
The files can also be opend using programs like winzip
The Field II program can now be run from this directory or from an other directory
where /home/user/field_II/m_files contains the Field II m-files. This
ensures that the directory is included in the Matlab search path, and the
user-written m-files can then be placed in a separate directory.
The individual files in the installation can be found
here. From this you can view
and download the individual m-files or the executable mex file
for Field II.
A number of utility files can be found
can be used for displaying the transducer geometry, etc.
The tar files for version 3.21 can be found below:
