6    
7    2008-04-22  Martin Maechler  <maechler@stat.math.ethz.ch>
8

45            ".tCMatrix" triangular matrix.
46    
47            * R/Auxiliaries.R (drop0): use diagU2N(); according to helpfile,
48            'clx' can be class *or* class representation.

50            (non0ind): new 'xtendSymm' argument; used in
51            * R/Ops.R:

63            (as0, as1): new utility.
64    
65            * R/Csparse.R (diag, band): need diagU2N()
66

68    
69            * R/lMatrix.R: coerce(nMatrix |-> lMatrix) fix

74    
75    2008-04-16  Martin Maechler  <maechler@stat.math.ethz.ch>
76

79    
80            * src/dsCMatrix.c (dsCMatrix_LDL_D): suppress 'CHOLMOD warning';
81            since we have our own error handler (and can use tryCatch() from R).

84    
85            * R/dgTMatrix.R (image): ha! set col=NA if lwd is small -- very nice!
86

88            when not positive definite.
89    
90            * R/Auxiliaries.R (asTri): new auxiliary
91            (non0.i): make *much* faster for Tsparse with many non-zero
92            entries; add 'uniqT = TRUE' argument to be used when sorting is undesired.
93    
94            * tests/Class+Meth.R (dotestMat): now build on checkMatrix() from
95            test-tools.R , see below
96

98    
99            * NAMESPACE, R/Matrix.R: add mean() method
100    
101    2008-04-12  Martin Maechler  <maechler@stat.math.ethz.ch>
102    
103            * R/dgTMatrix.R (image): allow to *not* take abs(), and use
104            cold-hot colors; try *changed* default useAbs = FALSE
105            * man/image-methods.Rd:  nice examples
106    
107    2008-04-11  Martin Maechler  <maechler@stat.math.ethz.ch>
108    
109            * inst/test-tools.R (checkMatrix): new function for modularizing part
110            of tstMatrixClass() in tests/Class+Meth.R
111    
112            * R/dsCMatrix.R: coercion from "matrix"
113            * R/ltTMatrix.R, R/ntTMatrix.R: ditto (change it).
114    
115            * tests/Class+Meth.R (tstMatrixClass): some cleanup;
116            add test for as(matrix(,0,0), <class>)
117    
118    2008-04-09  Martin Maechler  <maechler@stat.math.ethz.ch>
119    
120            * src/dgeMatrix.c (dgeMatrix_determinant): for n == 0,
121            work as determinant(matrix(,0,0)).
122    
123            * src/dgCMatrix.c (dgCMatrix_LU): return {L,U} as dtCMatrix
124            * man/sparseLU-class.Rd: ditto
125    
126            * R/dgCMatrix.R (determinant): method building on lu()
127            * R/sparseMatrix.R, Matrix.R, ...: ditto
128    
129            * R/Auxiliaries.R (mkDet): auxiliary for determinant()
130    
131    2008-04-07  Martin Maechler  <maechler@stat.math.ethz.ch>
132    
133            * R/sparseMatrix.R (summary<sparseMatrix>): no 'x' column for
134            pattern matrices.
135    
136  2008-04-02  Martin Maechler  <maechler@stat.math.ethz.ch>  2008-04-02  Martin Maechler  <maechler@stat.math.ethz.ch>
137    
138          * src/dense.c (dense_to_Csparse): all declarations *before*          * src/dense.c (dense_to_Csparse): all declarations *before*
