mul()
Description:
Calculate the product of two matrices or vectors.
Syntax:
mul(A, X)
Note:
The function calculates the product of multiplication of vector/matrix A and vector/matrix X, during which the vector X on the left will be automatically transposed.
Parameters:
|
A/X |
A matrix or a vector |
Return value:
Sequence
Example:
|
|
A |
|
|
1 |
[[3,5],[2,8]] |
|
|
2 |
[[4,6],[2,4]] |
|
|
3 |
=mul(A1,A2) |
