Object-oriented Transformations

Object-oriented Transformations#

The math module for whole BrainPy ecosystem. This module provides basic mathematical operations, including:

Details in the following.

`BrainPyObject`	The BrainPyObject class for the whole BrainPy ecosystem.
`FunAsObject`	Transform a Python function as a `BrainPyObject`.
`Partial`	A picklable, object-aware partial application of a function.
`NodeList`	A sequence of `BrainPyObject`, which is compatible with `vars()` and `nodes()` operations in a `BrainPyObject`.
`NodeDict`	A dictionary of `BrainPyObject`, which is compatible with `vars()` operation in a `BrainPyObject`.
`node_dict`
`node_list`
`Variable`	The pointer to specify the dynamical variable.
`Parameter`	The pointer to specify the parameter.
`TrainVar`	The pointer to specify the trainable variable.
`VariableView`	A view of a Variable instance.
`VarList`	A sequence of `Variable`, which is compatible with `vars()` operation in a `BrainPyObject`.
`VarDict`	A dictionary of `Variable`, which is compatible with `vars()` operation in a `BrainPyObject`.
`var_list`
`var_dict`

`grad`	Automatic gradient computation for functions or class objects.
`vector_grad`	Take vector-valued gradients for function `func`.
`jacobian`	Extending automatic Jacobian (reverse-mode) of `func` to classes.
`jacrev`	Extending automatic Jacobian (reverse-mode) of `func` to classes.
`jacfwd`	Extending automatic Jacobian (forward-mode) of `func` to classes.
`hessian`	Hessian of `func` as a dense array.
`cond`	Simple conditional statement (if-else) with instance of `Variable`.
`ifelse`	`If-else` control flows looks like native Pythonic programming.
`for_loop`	`for-loop` control flow with `Variable`.
`while_loop`	`while-loop` control flow with `Variable`.
`scan`	`scan` control flow with `Variable`.
`jit`	JIT (Just-In-Time) compilation for BrainPy computation.
`cls_jit`	Just-in-time compile a function and then the jitted function as the bound method for a class.
`to_object`	Transform a Python function to `BrainPyObject`.
`function`	Transform a Python function into a `BrainPyObject`.
`ProgressBar`	A progress bar for tracking the progress of a jitted for-loop computation.
