First of all, I couldn't find the answer in other questions. I have a numpy array of integer, this is called ELEM, the array has three columns that indicate, element number, node 1 and node 2. This is... go第五讲:运算符
Use the np.where "ufunc" to create a new array result_array based on the condition applied to condition_array. If the condition is True, the corresponding element from ‘array_1’ is chosen; otherwise, the element from ‘array_2’ is chosen. ...
