SymjaExpression

class SymjaExpression<T : Number, A : NumericAlgebra<T>>(val algebra: A, val mst: MST, val evaluator: ExprEvaluator = DEFAULT_EVALUATOR) : SpecialDifferentiableExpression<T, SymjaExpression<T, A>> (source)

Represents MST based space.kscience.kmath.expressions.DifferentiableExpression relying on Symja.

The principle of this API is converting the mst to an org.matheclipse.core.interfaces.IExpr, differentiating it with Symja's F.D, then converting org.matheclipse.core.interfaces.IExpr back to MST.

Parameters

T

The type of number.

A
