A basic overview of the Julia programming environment for numerical computations that we will use in 18.06 for simple computational exploration. This (Zoom-based) tutorial will cover what Julia is and the basics of interaction, scalar/vector/matrix arithmetic, and plotting — we'll be using it ...
An eigenvector of the square matrix A of order n is nonzero vector X such that AX=λX The scalar λ is called an eigenvalue of A, and X is called an eigenvector corresponding to or associated with λ. The eigenvalues may be determined from the characteristic equation |A−λI|=0 Th...
ParserNG is a powerful , fast math expression parser that parses and evaluates math expressions, does differential calculus(symbolic) evaluations, numerical integration, equation solving(quadratic, Tartaglia's, numerical solutions of other equations) , m

The (2s−1 − 1) × (2s−1 − 1) matrix in the right lower corner is again a block tridiagonal block Toeplitz matrix, so the reduction is recursively repeated until the system is reduced to a single block equation. (For an exercise, apply this algorithm to the system of Section...
Eigenvectors描述:if λ is an eigenvalue of A∈Rn×n then the non-zero vectors x∈Rn (x is an n-dim vector with complex elements) satisfying Ax=λx are the eigenvectors of A corresponding to the Eigenvalues λ 例:A= [2222],then the characteristic equation is det(A- λI )= [2−...
Use the fixed.complexQlessQRMatrixSolveFixedpointTypes function to analytically determine fixed-point types for the solution of the complex least-squares matrix equation Ports Input expand all A(i,:)—Rows of matrixA vector B(i,:)—Rows of matrixB ...
Update:TheExprTkproject looks interesting and seems like it can do some vector expression operations, as well as a bunch of stuff that EigenLab doesn't even try to do. However, I've not used it in any depth. If you don't need matrix operations, there are several equation parsers which...
In this equation, Θ is the vector of N−1 estimated phase values assuming the first image is zero, in other words, N−1 single-reference interferograms, Γˆ is the estimated complex coherence matrix obtained from normalizing the covariance matrix, H indicates Hermitian conjugation and ∘...
