See rad.simple.cov for a R coding of the radial basis functions. Value. If the argument C is NULL the cross covariance matrix. Moreover if x1 is equal to x2 then this is the covariance matrix for this set of locations. In general if nrow(x1)=m and nrow( x2)=n then the returned matrix, Sigma will be mXn.

Given two sets of locations these functions compute the cross covariance matrix for some covariance families. In addition these functions can take advantage of spareness, implement more efficient multiplcation of the cross covariance by a R is dependent on OS services (and they on FPUs) for floating-point arithmetic. On all current R platforms IEC 60559 (also known as IEEE 754) arithmetic is used, but some things in those standards are optional. In particular, %*% for matrix multiplication. Examples Details. exp and log are generic functions: methods can be defined for them individually or via the Math group generic.. log10 and log2 are only special cases, but will be computed more efficiently and accurately where supported by the OS.. Value.

where we have de ned the \matrix exponential" of a diagonalizable matrix as: eAt= Xe tX 1 Note that we have de ned the exponential e t of a diagonal matrix to be the diagonal matrix of the e tvalues. Equivalently, eAtis the matrix with the same eigenvectors as A but with eigenvalues replaced by e t.

The dimensions (number of rows and columns) should be same for the matrices involved in the operation. Matrix Addition & Subtraction 3) Fast matrix exponentiation. So, let’s discuss the 3rd one.

Appendix). Assume p has a uniform prior on the interval (0,1) and that r is fixed. (c) For the matrix exponential, prove that e(s+t)A = esAetA. 7.

Important note for package binaries: R-Forge provides these binaries only for the most recent version of R, but not for older versions.

This function computes the exponential of a square matrix \(A\), defined as the sum from \(r=0\) to infinity of \(A^r/r!\). Several methods are provided. The Taylor series and Pad approximation are very importantly combined with scaling and squaring. Usage There are a few different ways of creating a matrix exponentiation operator in R: we could create an R function and create an exponentiation operator for matrices, similar to the %*% matrix multiplication operator that exists already, or we could write the function in C and link to it. However, recall that the rate is not the expected value, so if you want to calculate, for instance, an exponential distribution in R with mean 10 you will need to calculate the corresponding rate: # Exponential density function of mean 10 dexp(x, rate = 0.1) # E(X) = 1/lambda = 1/0.1 = 10 The exponent 0 of a matrix will return its identity matrix instead of NULL.
