Hi all,
I am working with stack and I've created the following array arr:a,b,c],[d,e,f],[g,h,k;
I know how to extract just first elements using maplist(first, arr); or similar expression for the second. but how to get the following array:
sub_arr:a,b],[d,e],[g,h;
The motivation is to use the first two elements in each line for a MCQ and the last one for the creation of graphs for each choice.
Thanks in advance,
Rafi
Rafi,
I don't really use arrays. I just use matrices instead. Is there something else I should know about arrays (I don't pretend to know everything about Maxima yet...)
Did you checkout Maxima's "submatrix" command? I find it is very useful to use WxMaxima as a desktop application to play around.
M1:matrix([a,b,c],[d,e,f],[g,h,k]);
M2:submatrix(M1,3);

sublist1: map(lambda([a],[first(a),second(a)]), list1);.
