![]() ![]() Round a value towards the nearest rounded value. Round a value towards plus infinity If x is complex, both real and imaginary part are rounded towards plus infinity.Ĭalculates the power of x to y element wise.Ĭalculate the value of subtracting 1 from the exponential value.Ĭalculate the greatest common divisor for two or more values or arrays.Ĭalculate the hypotenusa of a list with values.Ĭalculate the (modular) multiplicative inverse of a modulo b.Ĭalculate the least common multiple for two or more values or arrays.Ĭalculate the 10-base logarithm of a value.Ĭalculates the modulus, the remainder of an integer division.Ĭalculate the norm of a number, vector or matrix. Solves the real-valued Sylvester equation AX XB=C for X, where A, B and C are matrices of appropriate dimensions, being A and B squared.Īttempts to determine if two expressions are symbolically equal, i.įinds one solution of a linear equation system by backward substitution.įinds all solutions of a linear equation system by backward substitution.Ĭalculate the absolute value of a number. Simplif圜ore() performs single pass simplification suitable for applications requiring ultimate performance.Ĭalculate the Sparse Matrix LU decomposition with full pivoting. Simplif圜onstant() takes a mathjs expression (either a Node representing a parse tree or a string which it parses to produce a node), and replaces any subexpression of it consisting entirely of constants with the computed value of that subexpression. Performs a real Schur decomposition of the real matrix A = UTU’ where U is orthogonal and T is upper quasi-triangular. Resolve(expr, scope) replaces variable nodes with their scoped values. Transform a rationalizable expression in a rational fraction. PolynomialRoot(constant, linearCoeff, quadraticCoeff, cubicCoeff)įinds the numerical values of the distinct roots of a polynomial with real or complex coefficients. Solves the Continuous-time Lyapunov equation AP PA’ Q=0 for P, where Q is an input matrix. Solves the linear system A * x = b where A is an matrix and b is a column vector. Gives the number of “leaf nodes” in the parse tree of the given expression A leaf node is one that has no subexpressions, essentially either a symbol or a constant.įinds one solution of a linear equation system by forwards substitution.įinds all solutions of a linear equation system by forwards substitution.Ĭalculate the Matrix LU decomposition with partial pivoting. Takes the derivative of an expression expressed in parser Nodes.
