\vec{v}=\begin{bmatrix}v_1\\v_2\end{bmatrix}的话，那这就是个简单的基变换：\begin{bmatri...
可以认为运动的A点就是直线ax+by=CA对应的无数条A_ xa+A_ yb=C交于一点
or a Van Atta retrodirective array in the lower band, but automatically turns into a beam-switching array based on a Butler matrix in the upper band... 周冠廷 被引量: 0发表: 2014年 Applications to Heterogeneous Integrated Phased Arrays: Design, Circuit Implementation, and Phased Array Applicatio...
cell array Approximation coefficients at each level of the transform, returned as an L-by-1 cell array of real-valued scaling (lowpass) coefficients, where L is the level of the transform. If X is a matrix, each element of D is a matrix whose column dimension equals the column dimension...
In anesthetized rats, we measured with the same array a significant drop in glucose concentration matched to a rise in lactate and concurrently with pronounced changes in the spectral profile of LFP-related currents during episodes of mechanically-evoked SD. This occurred along with the stereotypical...
// // Then the jacobian of the mapping, dy/dx, is the 3x4 sub-matrix of the // extended y vector, indicated in the above diagram. 与dual类似,jet一开始将各自变量携带伴随的表示微分的向量初始化成了一个接近于单位阵的东西,然后通过重载运算符,将这个伴随的向量的元素间相乘设定为0,即可实现一次...
Wavelet coefficients subband gains, specified as a real-valued matrix with a row dimension of L, where L is the number of elements in D. There are six columns in DetailGain for each of the six wavelet subbands. The elements of DetailGain are real numbers in the interval [0, 1]. The...
for i = 0, 1, where (⋅)T denotes the matrix transpose. The first term in (22) shows the state of the composite system if the photon is not discarded. In case the photon is absorbed by the electron, the state of the composite system collapses to the second term in (22). ...
The PAF beamformer is calibrated with observations of an unpolarized astronomical radio source, the covariance matrix of all receiver channels is calculated, and the two dominant eigenvectors are then used as beamformer weights. We show measurements demonstrating the capabilities of this instrument as ...
