Instance Methods

[hide private]

__init__(self, arg)
Initialization of asin Symbol with argument arg.

typically Symbol but other types such as float, escript.Data, numpy.ndarray are possible

diff(self, arg)
Differential of this object.

str

getMyCode(self, argstrs, format='escript')
Returns program code that can be used to evaluate the symbol.

escript.Symbol, float, escript.Data, numpy.ndarray depending on the degree of substitution

substitute(self, argvals)
Assigns new values to symbols in the definition of the symbol.

Method Details

[hide private]

init(self, arg)
(Constructor)

Initialization of asin Symbol with argument arg.

Parameters:

arg (typically Symbol) - argument of function

Overrides: object.__init__

diff(self, arg)

Differential of this object.

Parameters:

arg (escript.Symbol) - the derivative is calculated with respect to arg

Returns: typically Symbol but other types such as float, escript.Data, numpy.ndarray are possible

derivative with respect to arg

Overrides: Symbol.diff

getMyCode(self, argstrs, format=`'escript'`)

Returns program code that can be used to evaluate the symbol.

Parameters:

argstrs (str or a list of length 1 of str) - a string for each argument representing the argument for the evaluation
format (str) - specifies the format to be used. At the moment only "escript", "str" and "text" are supported.

Returns: str

a piece of program code which can be used to evaluate the expression assuming the values for the arguments are available

Raises:

NotImplementedError - if no implementation for the given format is available

Overrides: Symbol.getMyCode

substitute(self, argvals)

Assigns new values to symbols in the definition of the symbol. The method replaces the Symbol u by argvals[u] in the expression defining this object.

Parameters:

argvals (dict with keywords of type Symbol) - new values assigned to symbols

Returns: escript.Symbol, float, escript.Data, numpy.ndarray depending on the degree of substitution

result of the substitution process. Operations are executed as much as possible.

Raises:

TypeError - if a value for a Symbol cannot be substituted

Overrides: Symbol.substitute
