WebSingle element indexing works exactly like that for other standard Python sequences. It is 0-based, and accepts negative indices for indexing from the end of the array. >>> x = np.arange(10) >>> x[2] 2 >>> x[-2] 8. It is not necessary to separate each dimension’s index into its own set of square brackets. WebThe output, Lia, is a column vector. Lia = ismember (A,B,'rows') treats each row of A and each row of B as single entities and returns a column vector containing logical 1 ( true) where the rows of A are also rows of B. Elsewhere, the array contains logical 0 ( false ). The 'rows' option does not support cell arrays, unless one of the inputs is ...
