ArrayToVector(), A2V()
Summary
Copies an array to a vector.
Changes
Added to Version 6.0/2012.
Syntax
vec = ArrayToVector(array arr [, array options])
| Argument | Contents |
|---|---|
| arr | The array to convert to a vector |
| Options | Type | Contents |
|---|---|---|
| Row Based | String | "True" (the default) means v.rowbased will be "True"; "False" means v.columnbased will be "True" |
| Type | String | The type of number ("Double", "Float", "Long", or "Short"), or the type "String" |
Returns
A vector.
Notes
The options array is an optional argument.
If no Type is provided, the array elements are scanned and a reasonable type is chosen. Double will be chosen rather than Float to prevent loss of precision.
If an array element cannot be converted to the Type of the vector, it is set to null.
Can also be called as A2V().
For more information on vectors, see Vectors.
Examples
arr = {1, 3, 5.6, 7, 9}
vec = ArrayToVector(arr)
ShowArray({vec}) // vec = 1.0, 3.0, 5.6, 7.0, 9.0 as doubles
arr = {1, 3, 5.6, "7", 9}
vec = ArrayToVector(arr)
ShowArray({vec}) // vec = "1", "3", "5.6", "7", "9"
arr = {1.2, 3.4, 5.6, "7", 9}
vec = ArrayToVector(arr, {{"Type","Float"}})
ShowArray({vec}) // vec = 1.2, 3.4, 5.6, null, 9.0See Also
