6.9 Container construction functions

array[] real linspaced_array(int n, data real lower, data real upper)
Create a real array of length n of equidistantly-spaced elements between lower and upper
Available since 2.24

array[] int linspaced_int_array(int n, int lower, int upper)
Create a regularly spaced, increasing integer array of length n between lower and upper, inclusively. If (upper - lower) / (n - 1) is less than one, repeat each output (n - 1) / (upper - lower) times. If neither (upper - lower) / (n - 1) or (n - 1) / (upper - lower) are integers, upper is reduced until one of these is true.
Available since 2.26

vector linspaced_vector(int n, data real lower, data real upper)
Create an n-dimensional vector of equidistantly-spaced elements between lower and upper
Available since 2.24

row_vector linspaced_row_vector(int n, data real lower, data real upper)
Create an n-dimensional row-vector of equidistantly-spaced elements between lower and upper
Available since 2.24
