We need support for derivatives of matrix expressions with symbolic powers.

While experimenting with symbolic derivation by matrices, I came across the following strange behavior. Do I need a special function to sum up two expressions or is it a bug?
# Code
import sympy a…

Automatic evaluation of symbolic expressions of "numerics" prevents construction of such expressions despite them being perfectly numerically approximatable (or otherwise useful) if exact evaluation…

In extension of `SymbolicSubring`, we introduce rings of symbolic expressions with a fixed set of symbolic assumptions. Arithmetic within such a ring is allowed to use the assumptions for simplifica…

The bug seems to be related to the relatively new addition to python "sys.set_int_max_str_digits()" which I am not sure if it is possible to change within Octave.
See example 3 below for something th…

This is a somewhat subtle issue if the function is a pure python function (you'd need to analyze the argument names), but maybe a convention is that if variable names are specified, they must match …

The following small graph with a indirection (double index lookup) in a tasklet breaks under `simplify` passes:

sdfg = dace.SDFG('test_')
state = sdfg.add_state()

This came up looking at the "bubble shear" case which has a time-dependent advective velocity which is implemented through a symbolic expression which includes a Constant `t` which is updated in the f…
