static member CreateFromFunction : 
        rowCount : int * 
        columnCount : int * 
        initializer : Func<int, int, 'T> * 
        ?mutability : ArrayMutability *

(* 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, column pair 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

Return Value

DenseMatrix<T>
A DenseMatrix<T>.
