Hello, If i have
X=rand(20,1)
Y=rand(20,1)
then i want to do
p1=[x(1) y(1)]
p2=[x(2) y(2)]
. . .
. . .
. . .
p20=[x(20) y(20)]
How can i intialize these p1 to p20 values with the help of loop instead of intiallizing manually?
The varaible needs to be updates as p1...p20.
Finally with structure P has terms p1...p20, with p1...p20 have their values from X and Y
Thanks in advance

variant use cell array
X=rand(20,1)
Y=rand(20,1)
p = mat2cell([X Y],ones(20,1),2)
bad version
for j1 = 1:size(X,1)
jc = num2str(j1);
eval(['p' jc '= [X(' jc '), Y(' jc ')]']);
end
So do not ever! Use the better 'p{1}' of the first variant instead of 'p1'

@developer: structs and cells are fine.

Good one, Jan! My mind was stuck with the struct().
