* na_func.c (na_sum_body,na_accum): created. * na_index.c (na_slice): created. * na_index.c (na_aref,na_aset): if the argument is an array, methods [],[]= return same shape as the array. e.g, a[[[0,1],[2,3]]] creates 2-D array. * na_index.c (na_serialize_struct,na_aref_aryindex,na_aref_single): Created.

* mk*.rb, depend: include code-generating scripts in distribution. * na_func.c, mkopfunc.rb: rename sub! => sbt!. * mkfuncs.rb: fix to work for Ruby ver 1.5.4.
2000-07-10 Masahiro Tanaka <masa>
* na_array.c: rename na_to_narray1 to na_ary_to_narray * na_array.c: reduce GC problem; delay registration of objects. change return value of na_to_narray0 from VALUE to struct NARRAY * reflect in na_ary_to_na, na_ary_to_na, na_ary_to_narray. * narray.h: add GetOrMakeNArray(obj,ary), FreeMadeNArray(obj,ary) * narray.c, na_index.c, na_func.c, na_fftw.c: change na_to_narray0 to GetOrMakeNArray/FreeMadeNArray. * narray.c (na_free): free memory of itself structure. * narray.c (na_mark): pass pointer to rb_gc_mark. * na_array.c (na_make_inspect): return if total<0. * na_index.c (na_ary_to_index, na_aref, na_aset): judge whether empty array. * naimage/demo/mandel.rb: Now no need for checking size. * test/testindex*.rb: print more description.
