Visual Basic

Public Shared Function FromFunction(Of T) ( 
	rowCount As Integer,

C++/CLI

public:
generic<typename T>
static DenseMatrix<T>^ FromFunction(
	int rowCount, 
	int columnCount, 
	Func<int, int, T>^ initializer, 
	ArrayMutability mutability = ArrayMutability::MutableValues, 
	bool checkMissingValues = false
)

static member FromFunction : 
        rowCount : int * 
        columnCount : int * 
        initializer : Func<int, int, 'T> * 
        ?mutability : ArrayMutability * 
        ?checkMissingValues : bool 
(* Defaults:
        let _mutability = defaultArg mutability ArrayMutability.MutableValues
        let _checkMissingValues = defaultArg checkMissingValues false
*)
-> DenseMatrix<'T>

Parameters

rowCount Int32: The number of rows in the new matrix.
columnCount Int32: The number of columns in the new matrix.
initializer Func<Int32, Int32, T>: A delegate that takes a row and column index and returns the value of the corresponding element.
mutability ArrayMutability (Optional): Specifies how the matrix's values may be changed. The default is mutable values.
checkMissingValues Boolean (Optional): Optional. Specifies whether operations involving the matrix should check for the presence of missing values. The default is false.

Type Parameters

T: The element type of the matrix.

Return Value

DenseMatrix<T>
A new DenseMatrix<T> initialized using the specified function.

Exceptions

ArgumentOutOfRangeException	rowCount or columnCount is less than zero.
ArgumentNullException	initializer is null.
