MATLAB: Data structure that handles variable size data elements.

variable size data elements

Can i accomodate various sized integers together in an array like arr1=[1(1bit), 3(2bits), 6(3bits), 14(4bits), 31(5bits), 55(6bits), 121(7bits), 255(8bits)..so on..]. I want the variable should use the optimal storage by means of using variable size representations to the various elements in an array(as per requirement).

You can make them a cell....

Read about cell.

C{1} = single(pi) ; 
C{2} = double(pi) ;

MATLAB: Storing a single in a structure is changing the data type

The data type is converted, if the field existed before and was filled with the data:

S   = struct([]);
S.a = [];  % Type: double
S.a(1:10) = single(1:10);  % Implicit conversion to double.
% But:
S.b(1:10) = single(1:10);  % S.b is a single, because it was 
                           % a single at the creation

This means, that your expectations are correct: The fields of a struct can contain data of different type. But this detail does not hit the point: "force it to stay as a single" - the code you have written forces it to be converted to double. So please post the relevant part of the code or a minimal working example to reproduce your observation.
