## Helpful macros for debugging Octave. ############################################################ ## Display a dim-vector object. define display-dims echo ndims: \ output $arg0.rep[-1] echo \ndims: \ output *$arg0.rep@$arg0.rep[-1] echo \n dont-repeat end document display-dims Usage: display-dims DIM_VECTOR Display the contents of an Octave dimension vector. end ############################################################ ## Display a dense array object. define display-dense-array echo array object: \ output $arg0 echo \ndimensions:\n display-dims $arg0.dimensions echo \nrep = \ output *$arg0.rep echo \nrep.data = \ output *$arg0.rep.data@$arg0.rep.len echo \n dont-repeat end document display-dense-array Usage: display-dense-array ARRAY Display the contents of an ordinary, i.e., dense Octave array. See also [display-sparse-array] for showing the contents of sparse Octave arrays. end ############################################################ ## Display a sparse array object. define display-sparse-array echo sparse object: \ output $arg0 echo \ndimensions.rep[0] = \ display-dims $arg0.dimensions echo \ndimensions.rep[1] = \ output $arg0.dimensions.rep[1] echo \nrep = \ output *$arg0.rep echo \nrep.d = \ output *$arg0.rep.d@$arg0.rep.nzmx echo \nrep.r = \ output *$arg0.rep.r@$arg0.rep.nzmx echo \nrep.c = \ output *$arg0.rep.c@($arg0.rep.ncols+1) echo \n dont-repeat end document display-sparse-array Usage: display-sparse-array SPARSE_ARRAY Display the contents of a sparse Octave array. See also [display-dense-array] for showing the contents of ordinary Octave arrays. end ############################################################ ## Display Octave debugging stack define show-octave-dbstack call show_octave_dbstack () end document show-octave-dbstack Usage: show-octave-dbstack Display the contents of the current Octave debugging stack. This is the function stack that the Octave interpreter is processing and will be different from the C++ stack being debugged with gdb. end
