print in a loop

Good morning\evening

how can i print p[1], p[2]... p[n] using for loop

I couldn't print using

for i=1:3
p[i]
end

OR

for i=1:3
p[i]
end

What is the correct way?

And ONE more question if a have array p =[p1;p2;p3] and have array q =[1 2 ; 3 4 ; 5 6] how can I let p1=[1 2], p2=[ 3 4] and p3=[5 6]

Regards

fprintf('\n')
for i=1:3
    fprintf('p[%d] ',i)
end
fprintf('\n')

or a fancy version with comma

fprintf('\n')
for i=1:3
    fprintf('p[%d]',i)
    if i~=3
    fprintf(', ')
    end
end
fprintf('\n')

2 question

q =[1 2 ; 3 4 ; 5 6]
p1=q(1,:);
p2=q(2,:);
p3=q(3,:);
p =[p1;p2;p3]

I hope that the question isn't homework related, don't just copy the code, try to understand how it works and if you have any further question just write a comment

thanks Mr. Paulo Silva for answering me

it is not a homework question

I just ask because I'am working in senio project

for question 2,, can it be done using for loop ?

[Paulo Silva]

Yes it can be done but you should read this first http://www.mathworks.com/matlabcentral/answers/143-how-do-i-make-a-series-of-variables-a1-a2-a3-a10

The way you should do it is:

q =[1 2 ; 3 4 ; 5 6]

p=cell(3,1); %preallocate one cell to store the result

for n=1:size(q,1)

p{n}=q(n,:); %save every line into each element of p, so p1 is p{1}

end

Instead of making a mess by creating several variables you do the same with just one variable, it's easy to work with and understand.
