Storing vectors in a cluster?

for i=2:10
  a=...
end

I want to store matrixes as an element of a set for every cycle. I know they can be stored in a vector but in my main code loop may returns different number of elements over time.

example:

 a=[2], a=[29 3], a=[3 2]
 and set should be:
 cluster={2, 29 3, 3 2}

Is this what you want?

 a=[2], a=[29 3], a=[3 2]
 and set should be:
 cluster={2, 29 3, 3 2}

a is your variable, then store to cluster?

Yes my loop is returning many vectors with different lengths. I want to store all vectors. And in the end of the code i should tell how many vectors i have stored. a=[1] , a=[2 5], a=[1 4 5]

all of these count as 1.

Answer 1

[Kevin Chng]

 a1=[2]; a2=[29 3]; a3=[3 2];

I will change them to cell array first for indexing, it is always my preference.

a(1)=num2cell(a1);
a(2)=num2cell(a2);
a(3)=num2cell(a3);

How to know the number of variable?

numVar = length(a); %or
numVar = numel(a); %or
numVar = size(a,2);

display your variable

a{:}

Answer 2

[KALYAN ACHARJYA]

a1=[2]; a2=[29 3]; a3=[3 2];
cluster=[a1,a2,a3];

Command Window

cluster

cluster =

       2    29     3     3     2

Note: In your question, if you represents the all vectors with same name then Matlab store the last last value only

a=[2], a=[29 3], a=[3 2]

a =

     2

a =

    29     3

a =

     3     2

But can i calculate how many vectors did i stored on this code ?
