Personal Profile:

Ben Barrowes received both his B.S. and M.S. degrees in Electrical Engineering from Brigham Young University in 1999, and the Ph.D. degree in 2004 from the Massachusetts Institute of Technology, Cambridge, MA. He was named top high school math student in the state of Utah (1991), received two Rocky Mountain Space Grant Consortium (RMSGC) grants, and was awarded an NSF graduate fellowship. During 2004/05, he was a Director's funded Postdoc at Los Alamos National Laboratory in the Physics Division. His research interests center on electromagnetic wave theory and modeling with applications including wind-wave interaction, electromagnetic scattering from the sea surface as well as from random media, nanoscale energy generation techniques, computer interface methodologies, electromagnetic induction models for nonspherical geometries, and biological electromagnetic phenomena. Other interests include automatic code conversion/translation and arbitrary precision computing.

Professional Interests:
Consultant specializing in fortran <-> matlab conversion/translation/validation/optimization.

Then when I run the mp_TESTING.m I encounter eith the same problem of Sascha Krauß . Can anyone help me?

I'm sorry, I haven't used it for a year and can't remember the solution. (Or even the problem.) Maybe I can have another look, when I'm back in office on Monday, but I don't think, that it will help much...

Hi, I have downloaded this toolbox but I dont know how it works. I have set the path of extracted toolbox in my Matlab's search path but it doesnt work!
Actually I have the same problem of Haula Dias.
14 May 2013 Multiple Precision Toolbox for MATLAB This toolbox defines a new mp class allowing multiple precision objects in MATLAB. Author: Ben Barrowes Dias, Hasula

Hi Sascha, can you please explain how you fixed that problem ? I'm getting the same error when I try to run the test program,i.e,

Undefined function or method 'mpfr_construct_dd' for input
arguments of type 'double'

I don't see a mfile with the same name ?!..
21 Feb 2013 toSingle Converts all numeric variables in the workspace, or optionally all doubles only, to single precision Author: Ben Barrowes Simon, Jan

The dynamic change of the types will reduce the memory footprint of a function, but it is very likely that the processing time will grow: Matlab's JIT acceleration is impeded by such dynamic changes. Some functions need 100 times longer afterwards compared to a explicit and direct creation of the variables in the wanted class.
