2008-03-27 Ewout van den Berg <[email protected]>
* generateProblem.m: fixed bug in handling additional parameters.
* problems/prob901.m: fixed problem with thumbnail generation due
to the change in problem data.
--------- Release 1.1.3 ------------------------------------------------
2008-03-25 Michael P. Friedlander <[email protected]>
* tools/rwt: added pre-compiled MEX interfaces for Matlab
- v.704 on Windows (.dll)
- v.7.5 (R2007b) on Linux (.mexglx)
- v.7.5 (R2007b) on Windows (.mexw32)
- v.7.5 (R2007b) on MacIntel (.mexmaci)
(Thanks to Igor Carron for this suggestion.) Also, changed the
extensions of m-file placeholders to ".mhelp" so that older
versions of Matlab have an easier time finding the .dll files.
* examples/exSeismic: load seismic data from the 'data' subdir,
and test for the CurveLab interface before running problem.
2008-03-24 Ewout van den Berg <[email protected]>
* problems/data/prob502_angiogram.mat: store mask, pdf, and
angiogram to avoid having to use 'twister' mode in rand
* problems/prob502.m: load data from file for default
problem. This avoids having to use the 'twister' mode in rand
which was added only in Matlab 7.4. Thanks to Igor Carron for
reporting this problem.
--------- Release 1.1.2 ------------------------------------------------
2008-03-21 Ewout van den Berg <[email protected]>
* problems/data/prob901_seismic.mat: replaced normalized data by
original data.
* opCrop.m: Added crop operator to `extract' rectangular regions
from other operators.
* opSum.m: Added sum operator to form the weighted sum of a set
of operators.
* opBlockDiag.m, opDictionary.m, opStack.m: Removed bug with
respect to complex weights.
* opToepGauss.m, opToepSign.m: Added Toeplitz-based measurement
operators with Gaussian and sign entries.
* dottest.m: Report ratio between y'*Ax and x'*A'y in case the dot
test fails. This helps find scaling related bugs in operators.
Thanks to Gilles Hennenfent for suggesting this feature.
* opisreal.m: Added function that returns 1 if results of
multiplication by the given operator are real, and 0
otherwise. Also added an equivalent isreal member function to
classOp.
2008-03-02 Ewout van den Berg <[email protected]>
* opsize.m: Added opsize to query the size of an operator. This
function works the same as the size function on matrices.
* opStack.m: Added this operator to vertically stack a set of
operators, similar to opDictionary which does this horizontally.
2008-02-15 Ewout van den Berg <[email protected]>
* generateProblem.m: Added 'version' option to query Sparco
version. Example: version = generateProblem('version');
2008-02-14 Ewout van den Berg <[email protected]>
* operators/opHadamard.m: Added multiplication by the Hadamard
matrix.
* operators/opGaussian.m: Also added checks in row
orthogonalization mode to see if number of rows does not exceed
the number of columns, in which case the normalization cannot
work.
* problems/prob007.m, problems/prob008.m: Use QR instead of ORTH
to generate orthogonal rows in A; speeds up problem generation.
2008-01-25 Ewout van den Berg <[email protected]>
* problems/prob501.m: Bug fixed in generating the observation b.
Thanks to Elaine Hale for reporting this bug.
* generateProblem.m: Added `lookup' option to get problem index
based on name. Example: index = generateProblem(name/index,'lookup');
2008-01-23 Ewout van den Berg <[email protected]>
* generateProblem.m: Added problem look up by name. Each data.info
now also has a sparcoID field by default.
Example: name = generateProblem(name/index,'getname');
* parseDefaultOpts.m: Added parsing for getname flag.
* problems/*: Added handling of the getname query.
2008-01-22 Ewout van den Berg <[email protected]>
* operators/opSplitComplex.m: Added new non-linear operator for
splitting complex numbers into its real and imaginary parts and
vice versa.
2008-01-15 Michael P. Friedlander <[email protected]>
* problems/*: Added short names to all problems as info.name.
2008-01-12 Michael P. Friedlander <[email protected]>
* sparcoSetup: Don't compile RWT if the MEX interfaces already
exist.
2007-11-27 Ewout van den Berg <[email protected]>
* problems/prob001.m: Set the normalize flag in the Heaviside
matrix to ensure the solution is indeed sparse. Without it there
is too. much energy in the columns of the Heaviside matrix which
gives a dense optimal solution.
* problems/prob001.m: Generate the signal locally and compute the
exact sparse solution.
--------- Release 1.1 --------------------------------------------------
2007-11-30 Ewout van den Berg <[email protected]>
* operators/classOp/mtimes.m, operators/classOp/size.m: Support
matrix and classOp operators in addition to functions. This
feature can be used to unify matrix vector multiplication as well
as to associated counters to matrices and existing classOp
instances.
--------- Release 1.0 --------------------------------------------------
