nPr(matrix1, matrix2) ⇒ matrix Returns a matrix of permutations based on the corresponding element pairs in the two matrices. The arguments must be the same size matrix. nPr([6,5;4,3],[2,2;2,2]) ¸ [3102 206] nSolve( ) MATH/Algebra menu nSolve(equation, varOrGuess) ⇒ number or error_string Iteratively searches for one approximate real numeric solution to equation for its one variable. Specify varOrGuess as: variable - or - variable = real number nSolve(x^2+5xì 25=9,x) ¸ 3.844... nSolve(x^2=4,x=ë 1) ¸ ë 2. nSolve(x^2=4,x=1) ¸ 2. Note: If there are multiple solutions, you can use a guess to help find a particular solution. For example, x is valid and so is x=3. nSolve() is often much faster than solve() or zeros(), particularly if the "|" operator is used to constrain the search to a small interval containing exactly one simple solution. nSolve() attempts to determine either one point where the residual is zero or two relatively close points where the residual has opposite signs and the magnitude of the residual is not excessive. If it cannot achieve this using a modest number of sample points, it returns the string "no solution found." nSolve(x^2+5xì 25=9,x)|x0 and r
