Dear Dinesh, it's hard to help with such a few information. you should tell in deatil what you are doing and what you are looking for. I.e., what are frames, I guess that are video frames, thus they are rgb matrices... pos target_size?

hi Dinesh Elayaperumal

You should first generate in Matlab 1*12 for example:

pop(i,:)=rand(1,12)......

for convert array 1*12 to 3*4 use reshape function matlab follow:

Newsol=reshape(pop,3,4);

so you should use in code array 1*12 but for output you can use reshape.

of course you can convert Newsol: 3*4 to 1*12 for example:

arraynew=reshape(Newsol,1,12);

Thanks for your reply Mr. Niccolo Dematteis.

currently am working in object tracking using correlation filter (Matlab). i need to store my tracked object positions result into .mat file, and compare my result with OTB tracker benchmark.

I understand the topic of your project, but it is still unclear what of data you are dealing with. I mean, what is the size of the frame variable? How do you obtain pos target_sz ? I can't understand the meaning of the second line, but it seems that pos_target_sz has at least 4 components.

I can guess that, but tell me whether I'm right:

-you have 3 frames

-'pos_target_sz' is a vector of size 1x4 and you have 3 -'pos_target_sz' variables

-you're storing in 'positions' the 'pos_target_sz' data

therefore you obtain a 3x4 matrix

-you need a result 1x12 of the kind:

[ [pos_target_size(of frame 1), pos_target_sz(of frame 2), pos_target_sz(of frame 3)].

-therefore you need to use the reshape function as suggested by Human Shayanfar.

-But to do that, you should before define 'position' in a different way:

position(:,frame)=[pos_target_sz(:)]

-in the second line you have to change the postion of the indices accordingly

-and finally you must use reshape as follows:

results=reshape(results,1,12)
