Python Question

I have two matrices

`a = [[1,2][3,4]]`

b = [[5,6][7,8]]

I want to get the element-wise prodcut which will be

`[[1*5,2*6][3*7,4*8]]`

`[[5,12][21,32]]`

I tried with numpy

`print(np.dot(x,y))`

and

`print(x*y)`

result:

`[[19 22][43 50]]`

which gives me the matrix multiplication result not element-wise product. How can I get the the element-wise product aka. Hadamard product using built-in functions ?

Answer

Try this,

```
import numpy as np
a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])
np.multiply(a,b)
```

**Result**

```
array([[ 5, 12],
[21, 32]])
```
