'Declaration
Function MMult ( _
Arg1 As Object, _
Arg2 As Object _
) As Object
'Usage
Dim instance As WorksheetFunction

Dim Arg2 As Object
Dim returnValue As Object
returnValue = instance.MMult(Arg1, Arg2)
Object MMult(
Object Arg1,
Object Arg2
)
Parameters
Arg1
Type: System.ObjectArray1, array2 - the arrays you want to multiply.
Arg2
Type: System.ObjectArray1, array2 - the arrays you want to multiply.
Return Value
Type: System.Object
Remarks
The number of columns in array1 must be the same as the number of rows in array2, and both arrays must contain only numbers.
Array1 and array2 can be given as cell ranges, array constants, or references.
MMult returns the #VALUE! error when:
Any cells are empty or contain text.
The number of columns in array1 is different from the number of rows in array2.
The size of the resulting array is equal to or greater than a total of 5,461 cells.
The matrix product array a of two arrays b and c is:
