| Description: | generates a new matrix using the upper part of the input matrix |
| Usage: | T = IBTresort(matr) | |
| Input: | ||
| matr | Matrix: upper triangular matrix, the number of the rows is equal to the number of the columns | |
| Output: | ||
| T | Matrix: (2*rows(matr)-1)*rows(matr) matrix, the non-zero elements in T corresponding to the different elements in matr, others are 0 | |
