Hello,
I try to write fuction that return a list of number in range [a,b] with step
k, but first i try in command window this code:
/* This work in command window without variables */
kill(all);
m:[];
for i:0 step -3 thru 10 do (m:append(m, [i]), display(i));
display(m);
Here is OK, but this below is not OK:
/* This does NOT work in command window with variables */
kill(all);
a:0;
b:10;
k:-3;
m:[];
for i:a step k thru b do (m:append(m, [i]), display(i));
display(m);
/* here is the intresting the output */
(%i7) for i:a step k thru b do (m:append(m, [i]), display(i));
i = 0
i = - 3
i = - 6
....
and so on.
