stay Python Use in numpy Encountered a function dot function , Point multiplication function , Specific internal principles and usage , Record here :
One dimensional matrix
The first is the operation of one-dimensional matrix :
Its operation is directly multiplied :
One dimensional matrix is actually the multiplication of each corresponding point , Then I add
Two dimensional matrix
The dot product of the corresponding two-dimensional matrix is , If a.dot(b),a The line and the way of life b The number of columns is equal , And every element of the line , Multiply by each element of the column .
The internal principle is :[0 2 3 1] Respectively and [12][12][15][12] Multiply
For the above numpy Inside the warehouse dot Basic principle of function ;
