gensbi.utils.math#

Mathematical utility functions for GenSBI.

This module provides mathematical operations and transformations used throughout the library, including dimension expansion and divergence computation for vector fields.

Functions#

`_expand_dims`(x)	Expand dimensions of an array to have at least 3 dimensions.
`_expand_time`(t)	Expand time array to have at least 2 dimensions.
`divergence`(vf, t, x[, args])	Compute the divergence of a vector field at specified points and times.

Module Contents#

gensbi.utils.math._expand_dims(x)[source]#

Expand dimensions of an array to have at least 3 dimensions.

Parameters:: x (Input array to expand.)
Return type:: Array with at least 3 dimensions.

gensbi.utils.math._expand_time(t)[source]#

Expand time array to have at least 2 dimensions.

Parameters:: t (Time array to expand.)
Return type:: Time array with at least 2 dimensions.

gensbi.utils.math.divergence(vf, t, x, args=None)[source]#

Compute the divergence of a vector field at specified points and times.

Parameters:

vf (The vector field function.)
t (The time at which to compute the divergence.)
x (The point at which to compute the divergence.)
args (Optional additional arguments for the vector field function.)

Return type:

The divergence of the vector field at point x and time t.
