摺疊或展開巢狀矩陣
1.
在工作表中，建立包含一或多個巢狀矩陣的矩陣。

顯示矩陣。

此巢狀矩陣會以摺疊狀態在所取代之原始矩陣元素的相同位置中顯示。方括弧表示每個巢狀矩陣的大小。
3.
若要展開巢狀矩陣並檢視其元素，請在
「矩陣/表格」
標籤的
「結果格式」
群組中，按一下
「摺疊巢狀矩陣」
。
<region id="ID0ESCTOB" top="672.00000000000011" left="57.600000000000009" xml:lang="zh_TW" height="230.2" width="367.06" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="41" xml:lang="zh_TW"> <eval xml:lang="zh_TW" xmlns="http://schemas.mathsoft.com/math50"> <id labels="VARIABLE" xml:space="preserve" xml:lang="zh_TW" label-is-contextual="true">A</id> <unitOverride xml:lang="zh_TW"> <placeholder xml:lang="zh_TW" /> </unitOverride> </eval> <resultFormat xml:lang="zh_TW"> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="true" xml:lang="zh_TW" /> </resultFormat> </math> </region>
