MATLAB has powerful mathematical computation capabilities, supporting matrix manipulation, linear algebra, calculus, statistical analysis, etc. Its extensive library of mathematical functions covers a wide range of mathematical algorithms in various fields, enabling users to perform complex numerical calculations...
I figured out the spectrum normalized was in reality a matrix, not a vector, exactly as you have said! It was due to a transposed by mistake matrix in multipllication by which the spectrum_normalized was obtained. Thank you for your answers and explanations! Sorry for the confusion... Ch...

我知道两个全矩阵乘法的下界是Ω(n^2)。我最初的想法是:(1)对下三角矩阵进行变换,(2)估计这种变换的时间复杂度。T(lower_triangular_matrix_multiplication(n))+O(lower_triangular_matrix_transformation(n))>Ω(full_matrix_multiplication(n)) = Ω(n^2) 现在,我只需要证明O ...

So why is Matlab (the MKL) so fast at dgemm (double-precision general matrix-matrix multiplication)? In simple terms:because it uses vectorization and good caching of data.In more complex terms: see the article provided by Jonathan Moore. ...
4 复数和复数矩阵 (Complex and complex matrix)复数用特殊字符i或j 表示。 55、i=sqrt(-1), 其值在工作空间显示为 0+1.0000i. 例: 输入 z=3+4i 或z=3+4j 结果一样。 MATLAB 中复数有下面的语句生成办法:z=a+b*i 或 z=r*exp(i*) 其中r为复数的模,为复数辐角的弧度数。复数的两种输入方法:...
matrix operations follow the normal rules of linear algebra. matrix multiplication: the number of columns in matrix a must be equal to the number of rows in matrix b. Common array and matrix operations a+b a-b a.*b a*b a./b a.\b a/b a\b a.^b Be careful to distinguish between...
