I've downloaded your software and am having problems with the times method.
I want to multiply a 3x3 matrix by a 3x1 matrix and get a type mismatch error. Your help file says that " The number or rows of Matrix2 parameter must be equal to number of columns of current Matrix" which I believe is the case.
The code I have used is:
Dim M1, M2, M3, M4 As Matrix
Set M1 = New Matrix
M1.Rows = 3: M1.Cols = 3
M1.Item(0, 0) = 3
M1.Item(0, 1) = 4
M1.Item(0, 2) = 5
M1.Item(1, 0) = 6
M1.Item(1, 1) = 7
M1.Item(1, 2) = 8
M1.Item(2, 0) = 9
M1.Item(2, 1) = 10
M1.Item(2, 2) = 11
Set M2 = New Matrix
M2.Rows = 3: M2.Cols = 1
M2.Item(0, 0) = 1
M2.Item(1, 0) = 1
M2.Item(2, 0) = 1
Set M3 = M1.Times(M2) <---------- Type mismatch error here!
Can you let me know why this doesn't work. More complicated functions such as inverse are working ok and multiplying 3x3 by 3x3 works.

When you use this statement:
Dim M1, M2, M3, M4 As Matrix
variables M1,M2,M3 are declared as Variants and only variable M4 is
declared as a Matrix variable.
Try this:
Dim M1, M2, M3, M4 As Matrix
Debug.Print TypeName(M1), TypeName(M4)
you will get : Variant Matrix
In order to have this problem fixed please replace the Dim statement as follows:
Dim M1 As Matrix, M2 As Matrix, M3 As Matrix, M4 As Matrix
