# array initialization function

### Syntax

• float[]/string[]/bool[] [value, value, ...]
• float[]/string[]/bool[] [value, value, ... ; value, value, ... ; ...]

### Parameters

1. value—(float, float[], string, string[] ,bool, bool[] )
Array element values. At least one element must be specified.

### Returns

An array containing all elements in the specified arrangement. The type of the array depends on the type of value. For example, a float[] array can be made from a mixture of float and float[] values.

### Description

#### 1D array

An array can be initialized by the concatenation of primitive values separated by a comma:

``const a = ["B", "C", "D"]                (3)[B,C,D]``

Beside primitive values, also arrays can be used to create new arrays:

``const b = ["A", a, "E"]                  (5)[A,B,C,D,E]``

#### 2D array

Primitive values and/or arrays can be arranged in several rows separated by a semicolon:

``````const a = [-1 ; -2]                      (2x1)
-1
-2
const b = [0:2 ; 3, 3, 3]                (2x3)
0   1   2
3   3   3
const c = [a, b ; b, a]                  (4x4)
-1   0   1    2
-2   3   3    3
0   1   2   -1
3   3   3   -2``````

### Example

#### Fibonacci numbers

``````fibonacci(n) = case n <= 2 : [0:n-1]
else        : fibonacci([0,1], n)

fibonacci(a, n) = case size(a) == n : a
else              : fibonacci([a, a[size(a)-2] + a[size(a)-1]], n)

Lot --> print(fibonacci(10))  // (10)[0,1,1,2,3,5,8,13,21,34]``````
