matlab的tsearchn函數(shù)如何使用?
|
|||
|
請問有沒有人用過 matlab的tsearchn函數(shù)? 我想查找一個點(diǎn)是不是在一個立方體內(nèi)部,程序怎么寫? |

TSEARCHN N-D closest simplex search. T = TSEARCHN(X,TES,XI) returns the indices T of the enclosing simplex of the Delaunay tessellation TES for each point in XI. X is an m-by-n matrix, representing m points in n-D space. XI is a p-by-n matrix, representing p points in n-D space. TSEARCHN returns NaN for all points outside the convex hull of X. TSEARCHN requires a tessellation TES of the points X obtained from DELAUNAYN. [T,P] = TSEARCHN(X,TES,XI) also returns the barycentric coordinate P of XI in the simplex TES. P is an p-by-n+1 matrix. Each row of P is the barycentric coordinate of the corresponding point in XI. It is useful for interpolation. |
