Array formulae are also a space saving option when several values must be calculated, since they are not very memory-intensive. In addition, arrays are an essential tool for carrying out complex calculations, because you can have several cell ranges included in your calculations. $[officename] has different maths functions for arrays, such as the MMULT function for multiplying two arrays or the SUMPRODUCT function for calculating the scalar products of two arrays.
由于数组公式不会占用大量内存，因此在需要计算多个值时，使用数组公式还可以节省空间。此外，由于可以在计算中包括多个单元格范围，因此在进行复杂计算时，数组也是非常重要的工具。$[officename] 为数组提供了不同的数学函数，如用于两个数组相乘的 MMULT 函数，或用于计算两个数组标量乘积的 SUMPRODUCT 函数。
