Web1st Method: Here we have taken an example of an array of size 11. These are first ‘n’ natural numbers. So, the sequence is starting from 1 onwards. If you noticed the above array, 7 is the missing element. Now we have to find out that 7 is missing in the above sequence. We know the formula for the first n natural number which is: n (n+1) / 2. WebConstruct a Toeplitz matrix. The Toeplitz matrix has constant diagonals, with c as its first column and r as its first row. If r is not given, r == conjugate (c) is assumed. Parameters: carray_like First column of the matrix. Whatever the actual shape of c, it will be converted to a 1-D array. rarray_like, optional First row of the matrix.
