linSolve() linSolve( SystemOfLinearEqns, Var1, Var2, ...) ⇒ list linSolve(LinearEqn1 and LinearEqn2 and ..., Var1, Var2, ...) ⇒ list linSolve({LinearEqn1, LinearEqn2, ...}, Var1, Var2, ...) ⇒ list linSolve(SystemOfLinearEqns, {Var1, Var2, ...}) ⇒ list linSolve(LinearEqn1 and LinearEqn2 and ..., {Var1, Var2, ...}) ⇒ list linSolve({LinearEqn1, LinearEgn2, ...}, {Var1, Var2, ...}) ⇒ list Returns a list of solutions for the variables Var1, Var2, ... The first argument must evaluate to a system of linear equations or a single linear equation. Otherwise, an argument error occurs. For example, evaluating linSolve(x=1 and x=2,x) produces an "Argument Error" result. Catalog > @List( ) @List(List1) ⇒ list Note: You can insert this function from the keyboard by typing deltaList(...). Returns a list containing the differences between consecutive elements in List1. Each element of List1 is subtracted from the next element of List1. The resulting list is always one element shorter than the original List1. list4mat() list4mat(List [, elementsPerRow]) ⇒ matrix Returns a matrix filled row-by-row with the elements from List. elementsPerRow, if included, specifies the number of elements per row. Default is the number of elements in List (one row). If List does not fill the resulting matrix, zeros are added. Note: You can insert this function from the computer keyboard by typing list@>mat(...). ln( ) ln(Value1) ⇒ value ln(List1) ⇒ list Returns the natural logarithm of the argument. For a list, returns the natural logarithms of the elements. If complex format mode is Real: Catalog > Catalog > /u keys If complex format mode is Rectangular: TI-Nspire™ Reference Guide 55
