A quadratic form is an expression in a number of variables where each term is of degree two. Every quadratic form can be represented by a symmetric matrix, to generate the quadratic form we pre-multiply the matrix by a single row vector containing the variables and post-multiply the matrix ...

The diag function can also be used to take a vector of length n and create an n× n square diagonal matrix with the values from the vector on the diagonal: >> v = 1:4; >> diag(v) ans = 1 0 0 0 0 2 0 0 0 0 3 0 0 0 0 4 So, the diag function can be used two way...

Implicit expansion also works if you subtract a 1-by-3 vector from a 3-by-3 matrix because the two sizes are compatible. When you perform the subtraction, the vector is implicitly expanded to become a 3-by-3 matrix. A = [1 1 1; 2 2 2; 3 3 3] ...
is harder to obtain and involves a matrix-valued analogue of the Pearson equation. The ingredients for the matrix-valued Pearson equation are obtained from a matrix-valued differential operator that is well suited for a Darboux factorization. The use of shift operators is a well-established techniq...
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 ∘...
Support vector regression is a promising method for time-series prediction, as it has good generalisability and an overall stable behaviour. Recent studies
