save()

Somehow though I suspect that might not be exactly what you want; if
not, then please indicate what format you want to store the data in.

i have a file "football.mat" which is made from yuv video sequences such as football00.yuv,football01.yuv etc. i dont know how it was created so when i used the whos function in matlab it showed

whos -file football.mat
Name Size Bytes Class

org_football 240x352x125 84480000 double array

Grand total is 10560000 elements using 84480000 bytes

So i would like to create a similar mat file for some other yuv video sequences.
i have used the code below to read the yuv sequences and create a matlab movie.
All i need is a mat file like the above one. Please help.

clear;
%***************
for i=1:150
i
indx=num2str(i,'%03d');
fid = fopen(['C:\video_sim\test_seq\coastguard\coastguard',indx,'.yuv'],'r');
s = fread(fid,[352 288],'uchar');
fclose(fid);
frames_t(:,:,i)=s';
end
frames=frames_t;
for j = 1:150
imshow(frames_t(:,:,j)/255);
Frm(j) = getframe;
end
fp_sec=10;

movie(Frm,2,fp_sec);

movie2avi(Frm,'C:\video_sim\test_seq\coastguard\coastguard.avi','fps',10,'compression','none','quality',100);

It appears likely that the matrix org_bootball would be the same kind of
content as you would get if you were to save your variable frames_t
