1、輸入memory，查看內(nèi)存

可能的最大數(shù)組: 11127 MB (1.167e+10 bytes) * 可用于所有數(shù)組的內(nèi)存: 11127 MB (1.167e+10 bytes) * MATLAB 使用的內(nèi)存: 2353 MB (2.467e+09 bytes) 物理內(nèi)存(RAM): 16261 MB (1.705e+10 bytes)* 受可用的系統(tǒng)內(nèi)存(物理內(nèi)存 + 交換文件)限制。

2、system_dependent memstats

定義一個較大的矩陣之后，看改變（Swap space明顯占用變多）：

如何增加虛擬內(nèi)存：

計算機→→右鍵→→屬性→→高級系統(tǒng)設(shè)置

→→高級→→性能→→設(shè)置

→→高級→→虛擬內(nèi)存→→更改

改完之后再看內(nèi)存：
