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...

Log-log convex programs Starting with version 0.1.3, cvxpylayers can also differentiate through log-log convex programs (LLCPs), which generalize geometric programs. Use the keyword argumentgp=Truewhen constructing aCvxpyLayerfor an LLCP. Below is a simple usage example ...
(A) Detection of viral RNA in 1, 3, 5, and 7 dpc nasal wash via qRT-PCR. Viral RNA was quantified as genome copies per milliliter and presented as log10 genome per milliliter as described in Materials and Methods. Each symbol represents a different animal (six PBS and six CVXGA1)....
