Mat Or Vec R

Examples mat or vec 3 1 mat or vec 3 2.

Mat or vec r. Mat or vec creates an nr by nc zero matrix if nc is greater than 1 and a zero vector of length nr if nc equals 1. The class mat represents an n dimensional dense numerical single channel or multi channel array. Typedef vec type channels vec channels one char for the type. In python numpy arrays implement the flatten method while in r the desired effect can be achieved via the c or as vector functions.

Or even a matrix the same dimensions as x temp1 so that x temp1 i j should be raised to mat lambda i j. Unlike c vectors it generally stores short vectors only a few elements. Usage mat or vec nr nc arguments. Perhaps this is the clearest approach.

Mat lambda matrix vec lambda ncol 2 nrow nrow x temp1 byrow true x temp1 mat lambda as for your desire to perform a different operation when vec lambda is zero one way is to use ifelse. Simulation analysis of using the lasso to forecast stock returns. Mat or vec creates an nr by nc zero matrix if nc is greater than 1 and a zero vector of length nr if nc equals 1. Create a matrix or a vector description.

Where type is one of uchar short int float double and the characters for each type are b s i f d respectively. Mat or vec creates an nr by nc zero matrix if nc is greater than 1 and a zero vector of length nr if nc equals 1. Numbers of rows and columns. In r function vec of package ks allows vectorization and function vech implemented in both packages ks and sn allows half vectorization.

N dimensional dense array class. Julia has the vec a function as well. Mat or vec base r documentation. Vec vector is a template class for numerical values.
