sicmutils.operator
expclj/s
(exp op)Returns an operator represented by a Taylor series expansion of $e^x$, applied
to op. This expanded series of operators is itself an operator that applies
each element to its argument.
Put another way: (exp g) to an operator g means forming the power series
I + g + 1/2 g^2 + ... + 1/n! g^n
where (as elsewhere) exponentiating the operator means n-fold composition.
Returns an operator represented by a Taylor series expansion of $e^x$, applied to `op`. This expanded series of operators is itself an operator that applies each element to its argument. Put another way: `(exp g)` to an operator g means forming the power series ``` I + g + 1/2 g^2 + ... + 1/n! g^n ``` where (as elsewhere) exponentiating the operator means `n`-fold composition.
expnclj/s
(expn op)(expn op n)Similar to exp, but takes an optional argument n that defines an order for
each term of the taylor series expansion.
Similar to `exp`, but takes an optional argument `n` that defines an order for each term of the taylor series expansion.
identityclj/s
Identity operator. Returns its argument unchanged.
Identity operator. Returns its argument unchanged.
make-operatorclj/s
(make-operator f)(make-operator f name)(make-operator f name context)Returns an Operator wrapping the supplied procedure f with the symbolic
name name. (name defaults to '???.)
Optionally accepts a context map that will be stored inside the
returned Operator.
Returns an [[Operator]] wrapping the supplied procedure `f` with the symbolic name `name`. (`name` defaults to `'???`.) Optionally accepts a `context` map that will be stored inside the returned [[Operator]].
operator?clj/s
(operator? x)Returns true if the supplied x is an instance of Operator, false
otherwise.
Returns true if the supplied `x` is an instance of [[Operator]], false otherwise.
