PackingMethod (Built-in Mathematica Symbol)

PackingMethod is an option for GraphPlot and related functions which specifies how disconnected components should be packed together in the layout produced.

ParallelCombine (Built-in Mathematica Symbol)

ParallelCombine[f, h[e_1, e_2, ...], comb] evaluates f[h[e_1, e_2, ...]] in parallel by distributing parts of the computation to all parallel kernels and combining the ...

PolynomialQ (Built-in Mathematica Symbol)

PolynomialQ[expr, var] yields True if expr is a polynomial in var, and yields False otherwise. PolynomialQ[expr, {var_1, ...}] tests whether expr is a polynomial in the var_i.

PositiveDefiniteMatrixQ (Built-in Mathematica Symbol)

PositiveDefiniteMatrixQ[m] tests whether m is a positive definite matrix.

PrecedenceForm (Built-in Mathematica Symbol)

PrecedenceForm[expr, prec] prints with expr parenthesized as it would be if it contained an operator with precedence prec.

PreemptProtect (Built-in Mathematica Symbol)

PreemptProtect[expr] evaluates expr, without any interruption from preemptive evaluations.

PrincipalValue (Built-in Mathematica Symbol)

PrincipalValue is an option for Integrate that specifies whether the Cauchy principal value should be found for a definite integral.

QRDecomposition (Built-in Mathematica Symbol)

QRDecomposition[m] yields the QR decomposition for a numerical matrix m. The result is a list {q, r}, where q is an orthogonal matrix and r is an upper-triangular matrix.

QuadraticIrrationalQ (Built-in Mathematica Symbol)

QuadraticIrrationalQ[x] gives True if x is a quadratic irrational and False otherwise.

ReadProtected (Built-in Mathematica Symbol)

ReadProtected is an attribute that prevents values associated with a symbol from being seen.
