hi bobbym,
Congratulations on your 'promotion'. I think it is an excellent move by MIF.

So your parents are/were very smart. You must have taken after them.
I'm gonna log off now and will be back in about an hour or an hour and a half.

Nope, they did not make it. I wonder how many other people in the world have not made it due to not having a chance? What a waste.

Yes,an oak!!!
Btw,I am really getting through with the first function which is the maker of the Identity Matrix.There is although a mistake and I don't know where.Could you check my code:
IdenMatrix (n, matrix):=
block( [i, j, a],
i: 1,
j: 1,
while i <= n do
(
while j <= n do
(
if i = j then
a[i, j]: 1
else
a[i, j]: 0,
i: i+1,
j: j+1
)
),
matrix:genmatrix(a, n, n)
);
And the output is:
[ 1 a a ]
[ 1, 2 1, 3 ]
[ ]
(%o13) [ a 1 a ]
[ 2, 1 2, 3 ]
[ ]
[ a a 1 ]
[ 3, 1 3, 2 ]

Hi;
Good practice to code it for yourself. But I should have mentioned
that Maxima has a built in identity function.
identity(3) yields

But why does it put a[i,j] whenever i<>j? I set it to 0 if i<>j.
And that function doesn't work for me.I will check '?? matrix' to see if there is a function for an identity matrix.

Maxima already has a built in identity function so do not worry.

Which function is that? Identity(n) and identity(n) don't work for me,but even if there is such a function,I want to make my own.It will be better for me.

Okay, but it is more serious that you are not getting these built in commands to work. We are trying to implement a PSLQ. If we get sidetracked we will never finish. What error message are you getting?

There is no error message.It just puts wrong 'numbers' into the matrix.

Hmmm. Could be a bug. What does it output for identity(2)?

identity(2) outputs 2.It doesn't make a matrix.

But that still doesn't help me find a function for making an identity matrix or fix my code.

One thing at a time. The list of commands on that page I gave might work and they might not. Do they work for you?
