# Interface ModelCenter::IArray
Last update: 16.07.2025
**Definition**: `ModelCenter/src/ModelCenter.odl` (line 421)
Base class for all array types. Has common functionality for getting/setting array sizes and getting/setting values as strings.
Arrays start at 0 length by default. So you must set the size before you can assign individual array elements.
**Inherits from**:
- [ModelCenter::IVariable](interfaceModelCenter_1_1IVariable.md#interfaceModelCenter_1_1IVariable)
**Inherited by**:
- [ModelCenter::IBooleanArray](interfaceModelCenter_1_1IBooleanArray.md#interfaceModelCenter_1_1IBooleanArray)

### Property length
**Definition**: `ModelCenter/src/ModelCenter.odl` (line 1)
```
long ModelCenter::IArray::length
```
Size of the array. Alias for the length property. Only useful if the array is 1 dimensional. Use the [getLength()](interfaceModelCenter_1_1IArray.md#interfaceModelCenter_1_1IArray_1a8a6965fe1217428d63d594384a634bfb), [setLength()](interfaceModelCenter_1_1IArray.md#interfaceModelCenter_1_1IArray_1ac632aa0e8bc7a6fcac41245e151beec8), numDimensions, or [setDimensions()](interfaceModelCenter_1_1IArray.md#interfaceModelCenter_1_1IArray_1af881060e37aae0ff4c2c2238683db950) methods and properties for multi-dimensional arrays On initialization, the array is 0 length by default. To fill in values on a newly created array, set the size/length first.

### Function setLength
```
void ModelCenter::IArray::setLength(long length, [optional] VARIANT dim)
```
Sets the length of the n'th dimension of the array
**Parameters**:
- **length**: New length of the n'th dimension of the array
- **dim**: The dimension to set. This uses a 0 based index, so 0 will set the first dimension, 1 the second, etc. If omitted, sets the first dimension
**Parameters**:
- long **length**
- *\[optional\]* VARIANT **dim**
**Return type**: void
**Reimplemented by**:

### Function setDimensions
```
void ModelCenter::IArray::setDimensions(long d1, [optional] VARIANT d2, [optional] VARIANT d3, [optional] VARIANT d4, [optional] VARIANT d5, [optional] VARIANT d6, [optional] VARIANT d7, [optional] VARIANT d8, [optional] VARIANT d9, [optional] VARIANT d10)
```
Sets the number of dimensions of an array and the length of each dimension in one call. An array initializes to 0 length. If any dimension of the array has 0 length, the whole array contains no data. You must set the array size before filling in values unless you are using the setArray() call.
**Parameters**:
- **d1**: length of the 1st dimension of the array
- **d2**: length of the 2nd dimension of the array. If omitted, the array is 1 dimensional
- **d3**: length of the 3rd dimension of the array. If omitted, the array is 2 dimensional
- **d4**: length of the 4th dimension of the array. If omitted, the array is 3 dimensional
- **d5**: length of the 5th dimension of the array. If omitted, the array is 4 dimensional
- **d6**: length of the 6th dimension of the array. If omitted, the array is 5 dimensional
- **d7**: length of the 7th dimension of the array. If omitted, the array is 6 dimensional
- **d8**: length of the 8th dimension of the array. If omitted, the array is 7 dimensional
- **d9**: length of the 9th dimension of the array. If omitted, the array is 8 dimensional
- **d10**: length of the 10th dimension of the array. If omitted, the array is 9 dimensional
**Parameters**:
- long **d1**
- *\[optional\]* VARIANT **d2**
- *\[optional\]* VARIANT **d3**
- *\[optional\]* VARIANT **d4**
- *\[optional\]* VARIANT **d5**
