Programming Question: How do you augment one matrix with another?

[cyrille de brébisson]

Hello

Quote:the flexibility of matrix construction and deconstruction.
augment(mat A, mat B) command.

In NUMERICAL mode (Home and non CAS programs)

Deconstruction is relatively easy as you can do things like:
M(r) to access a row
M(-c) to access a column
M(r,c) to access an element
M(r or -c or r,c):= to place vectors in locations...
SUB(M, {r,c},{r,c}) extracts a sub part of a matrix...
REPLACE(M1, {r,c}, M2) will place M2 at a given location in M1
I do seem to remember (not sure), that you can use lists in the 'storying' type commands and that they will be transformed into matrices as needed...

Now, back to your problem... I do not have an augment command, however, you can do:
M3:=MAKEMAT(0, r, c); REPLACE(M3,{1,1},M1); REPLACE(M3,{0,c}, M2);
3 commands, but no loops or the like...
