augment(A, B, C, ...) Returns an
array formed by placing A, B, C, ... left to right.
stack(A , B, C, ...) Returns an
array formed by placing A, B, C, ... top
to bottom.
submatrix(A, ir, jr, ic, jc) Returns
the matrix consisting of rows ir through jr and columns ic through jc of array A.
Arguments:
A, B, C , ... are
arrays having the same number of rows for augment, or the same
number of columns for stack.
ir, jr are the integer upper
and lower indices of the rows to be extracted.
ic, jc are the integer upper
and lower indices of the columns to be extracted.
Notes:
A, B, C , ... can
be scalars and single-row arrays for augment, or scalars and single-column
arrays for stack.
Matrix and vector elements, rows, and columns are
numbered starting with zero, unless you change the ORIGIN.
To extract a single column, use the superscript
operator. To extract a single row, use the row
operator. You can add and delete multiple rows and columns using the Insert Matrix dialog box.
