A matrix is a concise and useful way of uniquely representing and working with linear transformations. In particular, every linear transformation can be represented by a matrix, and every matrix corresponds to a unique linear transformation. The matrix,
If you want the matrix inverse of alpha, well that's impossible to actually find (you can do some funny things with pseudo inverses but they're not real inverses). If none of that is what you are looking for then you need to ask a new question and better define what it is you are...

To further characterize the spatial layout of each diffusive matrix, we classified all cortical nodes into seven brain communities44 and calculated the average diffusive probabilities within the same system and between different systems separately across brain nodes. Notably, we observed that the ...
Matrix elements (such as Na, Ti, Fe, Mg, and Al) in each eluted Cu fraction were then checked by ICP-MS to improve the final accuracy of the Cu isotope analysis (see Huang et al., 2017 for the detailed procedure). Copper contents in the elution collected before and after the Cu ...
当我们把序列看成是一个n维实数向量 X(t) 时,我们有自相关矩阵(auto-correlation matrix)是任意两个时间 t_1,t_2 之间定义的矩阵: 自相关矩阵 而自协方差矩阵(autocovariance matrix)定义为: E[[x(t_1)-E[x(t_1)]][x(t_2)-E[x(t_2)]]^T] \tag{17} 这两者的差别其实就在于autocovariance ...
where σa are the Pauli matrices, σ0 the identity matrix, a is the pseudospin index and i is the spatial index; the vector q is the momentum measured from the Weyl point; E0 is the energy of the Weyl point. The first term \({\hat{H}}_{{\rm{W}}}\) contains information about...
傅里叶逆变换(Inverse Fourier Transform, IFT):f(t)=12π∫F(ω)⋅ejωtdω 看到这两个公式是不是看不懂?不要慌,慢慢看下去。看懂本文的数学基础:三角函数(波形)、级数(有规律的数的集合)、微积分(定积分)。 通俗理解什么是傅里叶变换?
