Sage 9.5 Release Tour
current development cycle (2021)
Contents
Symbolics
symbolic_expression is now able to create vectors and matrices of symbolic expressions for more general inputs. #16761
- For example, if the input is a list or tuple of lists/tuples/vectors:
sage: M = symbolic_expression([[1, x, x^2], (x, x^2, x^3), vector([x^2, x^3, x^4])]); M [ 1 x x^2] [ x x^2 x^3] [x^2 x^3 x^4] sage: M.parent() Full MatrixSpace of 3 by 3 dense matrices over Symbolic Ring
- For example, if the input is a list or tuple of lists/tuples/vectors:
Symbolic expressions can no longer be called with positional arguments. #14270
This was deprecated since Sage 4.0, although a bug prevented the deprecation warning from being issued in Sage versions 8.4 to 9.3. #32319
Instead of (x+1)(2), write either (x+1)(x=2), or (x+1).subs(x=2), or ((x+1).function(x))(2).

Deprecated and removed functionality
The package sage.media is now deprecated. #12673
The module sage.stats.basic_stats is now deprecated. #29662
In the deprecation messages, we point users to suitable numpy, and scipy.stats, and pandas functions. (Python 3 also comes with a basic ​built-in stats module, but much of its functionality is unfortunately incompatible with SageMath's number types, #28234.)
