matlab中如何实现连乘

[heartrain1987]

例如使用牛顿插值20次多项式，其中
Π（x-xi）
如何实现？
（不希望使用for循环，matlab中是否有自带函数）

当然是prod函数了：
PROD Product of elements.
For vectors, PROD(X) is the product of the elements of X. For
matrices, PROD(X) is a row vector with the product over each
column. For N-D arrays, PROD(X) operates on the first
non-singleton dimension.
