Hi bobbym

All of the commands on the page you gave me work for me.

It's version 5.26.

Btw,if it means anything to you,I have installed,all together,Euler Math Toolbox.

Well,maybe it is,maybe it isn't.I installed the one that came with the Maxima 5.26.0 package.

Why?I don't know anything about it!!!

Do you think it will be easier to make the algorithm work there?

It has the version of maxima that you are using.

Isn't it vice versa? I got the Toolbox when I downloaded Maxima.

Or do you mean it is using the same code compiler,syntax,has the same semantics,...as Maxima 5.26.0?

Hi bobbym

Did you try out the environment?

Try out some of the inputs from that page you gave me.

Yes, I did. I did not like it very much. I am going to try straight maxima 5.26

Ok.Cool.I am waiting.Do you have any idea on how to convert the algorithm into Maxima syntax?

You can use the command diagmatrix(n,1) to generate the identity matrix.

Hi bobbym

Have you at least figured out how to create an identity matrix?

Actually,I figured out what was wrong.I was increasing i at the same time as j.I will post my new code as soon as I fix it.

hi bobbym

```
IdenMatrix(n):=
block( [i, j, a, m],
i: 1,
while i <= n do
(
j: 1,
while j <= n do
(
if i = j then
a[i, j]: 1
else
a[i, j]: 0,
j: j+1
),
i: i+1
),
m: genmatrix(a, n, n)
);
```

Use diagmatrix(n,1) instead.
