Joining and Subdividing Arrays
• 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.
To extract a single column, use the column operator. To extract a single row, use the row operator.
Arguments
• A, B, C , ... are arrays having the same number of rows for augment, or the same number of columns for stack.
A, B, C , ... can be scalars and single-row vectors for augment, or scalars and single-column vectors 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.
