ILNumerics - Technical Application Development

An array with the same shape of A, except dimension 'axis' which is reduced / expanded to length 1.

[numpy API] Create an array with the mean of elements of A along a single dimension.

**Namespace:**ILNumerics**Assembly:**ILNumerics.numpy (in ILNumerics.numpy.dll) Version: 5.5.0.0 (5.5.7503.3146)Syntax

public static RetArray<double> mean( this ConcreteArray<long, Array<long>, InArray<long>, OutArray<long>, RetArray<long>, Storage<long>> A, int axis, bool keepdims = false )

#### Parameters

- A
- Type: ILNumerics.Core.ArraysConcreteArrayInt64, ArrayInt64, InArrayInt64, OutArrayInt64, RetArrayInt64, StorageInt64

The source array. This will not be altered. - axis
- Type: SystemInt32

The dimension to compute the mean of A along. - keepdims (Optional)
- Type: SystemBoolean

[Optional] the reduced dimension axis remains in the resulting array. Default: (false) the dimension axis is removed from the result.

#### Return Value

Type: RetArrayDoubleAn array with the same shape of A, except dimension 'axis' which is reduced / expanded to length 1.

#### Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ConcreteArrayInt64, ArrayInt64, InArrayInt64, OutArrayInt64, RetArrayInt64, StorageInt64. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).Remarks

Depending on the value of keepdims the array returned will have the same number of dimensions as A (keepdims = true) or with a number of dimensions according to MinNumberOfArrayDimensions (keepdims = false).

Empty arrays A produce a scalar array with the default element value for the element data type.
