Next, we’ll divide a 2-dimensional Numpy array by a scalar value. np.divide(matrix_2d_ordered, 2) OUT: array([[0.5, 1. , 1.5], [2. , 2.5, 3. ], [3.5, 4. , 4.5]]) Explanation Here, we’ve divided every value ofmatrix_2d_orderedby the scalar value 2. ...
Matlab treats any non-zero value as 1 and returns the logical AND. For example (3 & 4) in Numpy is 0, while in Matlab both 3 and 4 are considered logical true and (3 & 4) returns 1. Precedence: Numpy's & operator is higher precedence than logical operators like < and >; Matlab...
