If either t or b is zero, no rows are trimmed from that end of the matrix. Elements of a matrix and submatrices can also be extracted using the row and column indices as follows: x[r1:r2,c1:c2] extracts the submatrix consisting of rows r1 to r2 and columns c1 to c2. Using a single index for column and row obviously extracts just the rc-th element. ................
