Hi there~
I just created 3 matrix tables which are named
a23 <(2x3)
a34 <(3x4)
a45 <(4x5)

I also want to create a function for that
m2(...),m3(...),m4(...)
when i wrote the m2..m for matrix..2 for 2 unknowns,
I need to renew the table a23
------------
Math question
solve for x,y
x+y=2
2x+3y=5
easy>>x=1,y=1
i know it's easy
but for solving 5 unknowns..u will feel pain to do that..:(
-----------
so ax+by=c,dx+ey=f
m2(a,b,c,d,e,f)
change the numbers in tables
I did
[[a,b,c][d,e,f]]-> a23
then
rref(a23)

entire code:
m2(a,b,c,d,e,f)
[[a,b,c][d,e,f]]-> a23
rref(a23)


DOES NOT WORK :[
I DO NOT KNOW WHY :(
ANYONE CAN HELP ME OUT? :]
THANKS SO MUCH
