Matrix Creation

vector( n ) — vector of length n initialized to zero

vector( n, value ) — vector of length n initialized to a real value

vector( n, [value1,value2] ) — vector of length n initialized to random real values

matrix( n )n × n matrix initialized to zero

matrix( n, m )n × m matrix initialized to zero

matrix( n, m, value )n × m matrix initialized to a real value

matrix( n, m, [value1,value2] )n × m matrix initialized to random real values

identity( n )n × n real identity matrix

identity( n, value )n × n real identity matrix multiplied by a real value
