zeros: Zero Vector/Matrix

Description

Returns a vector or 2D matrix of zeros of the same shape as the input.

Usage

zeros (x,y=0)

Arguments

x

A scalar, vector, or two dimensional matrix.

y

An optional parameter to create a 2D matrix.

Details

If a scalar value is given, a vector of that many zeros is returned. If the y parameter is also specified, a matrix is returned with x rows and y columns. If a vector is given, a vector of zeros of the same length is returned. If a 2D matrix or dataframe is given, a matrix of zeros with the name number of rows and columns is returned.

Examples

## A vector 
zeros (5)
## A matrix
zeros (5, 3)
