Project Waterloo File and Matrix Utilities

Utilities for partial input/output from MATLAB MAT-files, HDF5-files and custom binary files.

Description

Utilities for partial input/output from MATLAB MAT-files, HDF5-files and custom binary files.

Appropriate use of the custom classes provided here can speed MATLAB code execution typically by 2- to 20-fold.

I/o is supported using
[1] virtual memory mapping of files (recommended: Version 6 MAT, HDF5 and binary files).
[2] low-level i/o using fread (Version 6 MAT- files /HDF5/binary).
[3] via the matlab.io.MatFile class for Version 7.3 MAT-files with R2011b+.

The previous MAT-file utilities for writing Version 6 MAT-files are included in the library.
Various functions for converting between file types are also included.

The full code is available for download at http://sigtool.sourceforge.net/

Um, why is there only a pdf and a txt file in the download? Where are the actual matlab files?

Malcolm straightened me out. Thank you! The files really do need to be -v6. Still wish there was a more flexible way to do this, but this is a nice start.

What was the error message?

[Kip]

Wish it worked! Using AppendMatrix with MATLAB version 7.9.0.529 (R2009b) I get:

Error in ==> where at 267
if strcmp(Name,'0123456789') && ~isempty(s(1).name)

Error in ==> CheckIsLastEntry at 35
w=where(filename, varname);

Error in ==> argcheck at 32
if CheckIsLastEntry(filename,varname)==false

Error in ==> AppendMatrix at 56
filename=argcheck(filename, varname);
