| 4.2.3 | Sep 20, 2024 | New Release | The value returned by `math.epsilon` for arguments around zero was too small or even `undefined`, also causing wrong results in `calc.differ` when computing the first derivative around zero. This has been fixed for both the first and second form of `math.epsilon`. stats.max` returned a wrong position for the maximum value of a distribution. This has been fixed, too. |
| 4.2.2 | Sep 18, 2024 | New Release | Changed memory management to prevent out-of-memory errors if you are working with very large structures: When internal memory for tables and sequences is to be expanded, Agena now increases it by around 13 percent (median) and not just to the next power of two, affecting a large number of operators and functions, including Cantor set operations on tables and sequences. You can explore the new method by calling the new function `utils.newsize`. Buffer arrays are now aligned to word boundaries (4-byte chunks). Buffers for integers and floating-point numbers are now also mildly expanded, benefitting, among others, the `union`, `intersect` and `minus` metamethods of the `numarray` package and functions `numarray.unique`, `io.lines`, `lookup.indices`, `tables.indices` and `tables.entries`. `sequences.resize` now just re-allocates memory to the next multiple of four instead of the next power of two, saving memory. This release has been Valgrind-checked on x86 and AMD64 Linux to ensure there are no internal errors or memory leaks. |
| 4.2.1 | Sep 17, 2024 | New Release | `numarray.double`, `numarray.longdouble`, `numarray.uchar`, `numarray.ushort`, `numarray.uint32` and `numarray.int32` can now be called without any argument. In this case the functions create a numeric array of size zero which you may fill later with `numarray.append`, `numarray.prepend`, `numarray.resize`, etc. The functions now also accept an initialising table, sequence or register and fill the numeric array (numarray) with the numbers in them: > a := numarray.double(3, [1, 2, 3]); > numarray.toseq(a): # inspect the contents seq(1, 2, 3) `numarray.include` can now insert more than one number into a numeric array with only one call. For example, to insert 10 and 20 at index 2 in numarray a, issue: > a := numarray.double(3, [1, 2, 3]); > numarray.include(a, 2, 10, 20); > numarray.toseq(a): # check the contents seq(1, 10, 20, 2, 3) `numarray.append` can now join two numarrays in-place. > a := numarray.double(3, [1, 2, 3]); > b := numarray.double(3, [10, 20, 30]); > numarray.append(a, b); > numarray.toseq(a): # inspect the contents seq(1, 2, 3, 10, 20, 30) New `numarray.prepend` adds one or more numbers to the beginning of a numarray. The function can also join two numarrays in-place. Examples: > a := numarray.double(3, [1, 2, 3]); > numarray.prepend(a, -1, 0); > numarray.toseq(a): # check the contents seq(-1, 0, 1, 2, 3) > a := numarray.double(3, [1, 2, 3]); > b := numarray.double(3, [-1, 0]); > numarray.prepend(a, b); > numarray.toseq(a): # inspect the contents seq(-1, 0, 0, 1, 2, 3) New `numarray.zip` zips together two numarrays with a user-defined function; for example to add the respective values at the same index, enter: > a := numarray.double(4, [1, 2, 3, 4]); > b := numarray.double(4, [2, 3, 4, 5]); > c := numarray.zip(<< x, y -> x + y >>, a, b); > numarray.toseq(c): # check the contents seq(3, 5, 7, 9) This release has been Valgrind-checked on x86 and AMD64 Linux to ensure there |
