Function is.fullrank [limma v3.28.14]
- keywords
- algebra
- title
- Check for Full Column Rank
- description
- Test whether a numeric matrix has full column rank.
Function get.eigentraits [cape v2.0.2]
- keywords
- algebra
- title
- Calculate eigentraits from phenotype matrix
- description
- This function performs the singular value decomposition (SVD) on the phenotype matrix after first removing individuals with missing data. The eigentraits are the left singular vectors of the decomposition. This function optionally mean centers and normalizes the phenotype matrix before performing the SVD.
Function projections [lspls v0.2-2]
- keywords
- algebra
- title
- Projection and Orthogonalisation
- description
- Functions to project one matrix onto another, or to ortghogonalise it against the other.

- algebra
- title
- The QR decomposition of a matrix
- description
- Computes the QR decomposition of a matrix.

Function svd.triplet [FactoMineR v1.41]
- keywords
- algebra
- title
- Singular Value Decomposition of a Matrix
- description
- Compute the singular-value decomposition of a rectangular matrix with weights for rows and columns.
Function SparseM.solve [SparseM v1.77]
- keywords
- algebra
- title
- Linear Equation Solving for Sparse Matrices
- description
- chol performs a Cholesky decomposition of a symmetric positive definite sparse matrix x of class matrix.csr. backsolve performs a triangular back-fitting to compute the solutions of a system of linear equations in one step. backsolve and forwardsolve can also split the functionality of backsolve into two steps. solve combines chol and backsolve and will compute the inverse of a matrix if the right-hand-side is missing.
Function SparseM.ontology [SparseM v1.77]
- keywords
- algebra
- title
- Sparse Matrix Class
- description
- This group of functions evaluates and coerces changes in class structure.
