02 May 2012	TPROD -- arbitary tensor products between n-d arrays TPROD -- efficiently allows any type of tensor product between 2 multi-dimensional arrays	Joao Hespanha	Sounds great, but I get accuracy error in tprod_testcases: **************** Double Real X, Single Real Y ****************** dRsR OuterProduct, [1],[2] = 5.96e-08 Passed dRsR Inner product, [-1],[-1] = 3.76e-08 Passed dRsR Matrix product, [1 -1],[-1 2] = 3.22e-06 Passed dRsR transposed matrix product, [-1 1],[-1 2] = 3.56e-06 Passed dRsR Matrix frobenius norm, [-1 -2],[-1 -2] = 6.94e-07 Passed dRsR transposed matrix frobenius norm, [-1 -2],[-2 -1] = 7.48e-07 Passed dRsR ignored dims, [0 -2],[-2 2 1] = 4.49e-06 Passed dRsR spatio-temporal filter [-1 -2 1],[-1 -2] = 7.2e-05 **FAILED*** The above was from MATLAB 7.14.0.739 (R2012a), OSX Xcode 4.3. I've also tried it with MATLAB 7.13.0.564 (R2011b), OSX Xcode 4.3 and I also get an accuracy error, but at a different spot: **************** Double Real X, Single Real Y ****************** dRsR OuterProduct, [1],[2] = 5.96e-08 Passed dRsR Inner product, [-1],[-1] = 2.88e-07 Passed dRsR Matrix product, [1 -1],[-1 2] = 2.94e-06 Passed dRsR transposed matrix product, [-1 1],[-1 2] = 3.55e-06 Passed dRsR Matrix frobenius norm, [-1 -2],[-1 -2] = 3.65e-05 **FAILED*** Warning: dRsR Matrix frobenius norm, [-1 -2],[-1 -2]: failed!

16 Oct 2011	Kalman Filter Tutorial Extended Kalman Filter Tutorial	benny goh	The observation function h is a linear function. Can it be a linear function for EKF?	Comment only
23 Aug 2011	TPROD -- arbitary tensor products between n-d arrays TPROD -- efficiently allows any type of tensor product between 2 multi-dimensional arrays	Fangjun Jiang	Please consider re-writing the help text to better explain the syntax. Some examples provided cause syntax error. See the link: http://www.mathworks.com/matlabcentral/answers/14046-i-didn-t-understand-how-put-the-inputs-in-tprod-function	Comment only
