Solve matrix in r
WebThe default method for as.matrix calls as.vector (x), and hence e.g.coerces factors to character vectors. When coercing a vector, it produces a one-column matrix, and promotes the names (if any) of the vector to the rownames of the matrix. is.matrix is a primitive function. The print method for a matrix gives a rectangular layout with dimnames ... Weba. a square numeric or complex matrix containing the coefficients of the linear system. Logical matrices are coerced to numeric. b. a numeric or complex vector or matrix giving the right-hand side (s) of the linear system. If missing, b is taken to be an identity matrix and solve will return the inverse of a. tol.
