CVX无法直接表示 log2x ,可以使用log(x)/log(2)表示。 由于trace(X)中,X必须是二阶方阵,如果使用W(M,M,K)表示提升后的波束成形矩阵,可以创造一个长度为K的数组来装每个W(:,:,k)的迹 CVX可以对向量或矩阵进行整体操作。 尽量不要使用SDP模式,因为SDP模式会修改矩阵不等式的定义 CVX一般不允许出现乘...
1.去官网找到cvx的安装包 2.下载,解压(不要解压到matlab的自带工具文件里面),如果你之前没有安装就可以随便放在一个文件夹。如果之前安装了,解压时不要覆盖旧版的 3.打开matlab,在命令窗口…阅读全文 赞同9 7 条评论 分享收藏 cvx使用记录 dddkkkfgd CVX无法直接表示 ,可以使用log(x)...

where the\(\alpha(p_n)\)term grows very slowly compared to the\(\log_2\)term. Indeed, for\(p_n\leq 4096\), we have verified that\(\alpha(p_n)\)is usually 1 or 2, but occasionally 0 or 3. Similar results are obtained for\(0 < p < 1\)and\(p < 0\). ...
