函数: solve()

solve(diagonal: number[], lower: number[], upper: number[], right: Cartesian3[]): Cartesian3[]

Solves a tridiagonal system of linear equations.

参数

diagonal

number[]

An array with length <code>n</code> that contains the diagonal of the coefficient matrix.

lower

number[]

An array with length <code>n - 1</code> that contains the lower diagonal of the coefficient matrix.

upper

number[]

An array with length <code>n - 1</code> that contains the upper diagonal of the coefficient matrix.

right

Cartesian3[]

An array of Cartesians with length <code>n</code> that is the right side of the system of equations.

返回

Cartesian3[]

An array of Cartesians with length n that is the solution to the tridiagonal system of equations.
