# Multiply

Returns: Array.

If an optional C matrix isn't passed then a new one is created and returned.

Argument	Description
A
B
C	An optional matrix to apply the multiplication to.

Multiply two matrices together and return the result.

# elements

The underlying data stored as an array.

matrix.js:26

# manual

Determines whether Two.js automatically calculates the values for the matrix or if the developer intends to manage the matrix.
