reshape(arr, -1) # Example 4: Convert numpy matrix to array # Use reshape() result = arr.reshape(-1) 2. Convert NumPy Matrix to Array Using flatten() We can use numpy.flatten() function to convert the matrix to an array. It takes all N elements of the matrix placed into a ...
To concatenate 2D arrays with 1D array in NumPy, we have different approaches, we can useravel()to flatten the 2D array and then we can use concatenate so that the result would be a 1D array with all the elements of both the array together. Secondly, we can use thecolumn_stack()method...
