creates a Vector from a list:

> fromList [2,3,5,7]
4 |> [2.0,3.0,5.0,7.0]

An alternative to fromList with explicit dimension. The input list is explicitly truncated if it is too long, so it may safely be used, for instance, with infinite lists.

This is the format used in the instances for Show (Vector a).

extracts the Vector elements to a list

> toList (linspace 5 (1,10))
[1.0,3.25,5.5,7.75,10.0]

creates a Vector of the specified length using the supplied function to to map the index to the value at that index.

> buildVector 4 fromIntegral
4 |> [0.0,1.0,2.0,3.0]

Reads a vector position:

> fromList [0..9] @> 7
7.0

creates a new Vector by joining a list of Vectors

> join [fromList [1..5], constant 1 3]
8 |> [1.0,2.0,3.0,4.0,5.0,1.0,1.0,1.0]

creates a vector with a given number of equal components:

> constant 2 7
7 |> [2.0,2.0,2.0,2.0,2.0,2.0,2.0]

Creates a real vector containing a range of values:

> linspace 5 (-3,7)
5 |> [-3.0,-0.5,2.0,4.5,7.0]

Logarithmic spacing can be defined as follows:

logspace n (a,b) = 10 ** linspace n (a,b)

Show a vector using a function for showing matrices.

disp = putStr . vecdisp (dispf 2)

> disp (linspace 10 (0,1))
10 |> 0.00  0.11  0.22  0.33  0.44  0.56  0.67  0.78  0.89  1.00
