3pts Create a method called "multiply" that takes a matrix and multiplies (dot product) this matrix against a matrix passed in and returns the result. If the shapes are incompatible, print "Shapes are incompatable" and return None. 

from the above posted question wat's a dot product ?? is it "matrix vector multiplication or some thing else ?? "

thanks in advance :)
