how to convert 2d data into 3d data?

hi everyone

i have a 2d matrix data (333 x 364) which is lat and lon information. i need to add time to this data (732 x 1). i extracted time from a different data and i need to attach time to the 2d data making it 3d.

nccreate('iteration1.nc','Long','Dimensions',{'Long',length(x1)},'Format','64bit');
ncwrite('iteration1.nc','Long',x1);
nccreate('iteration1.nc','Lat','Dimensions',{'Lat',length(y1)},'Format','64bit');
ncwrite('iteration1.nc','Lat',y1);
nccreate('iteration1.nc','emission','Dimensions',{'Lat',length(y1),'Long',length(x1)},'Format','64bit');
ncwrite('iteration1.nc','emission',newemission');

the above code was used to make the 2d output data. x1 is the longitude, y1 is lattitude and new emission has the data. so in order to add a third dimension i need to make newemission into a 3d data from 2d. so how do i make newemission into a 3d data from 2d? i have time (732 x1 ) as a separate variable. i need to attach it to newemission. kindly give me suggestion on how to do it. thank you.

Say you have one frame from a video, and you have a vector describing the timestamps for the next 700 frames. How would you turn that one frame back into a video?

There are trivial solutions. You could replicate the data, or you could fill it all with zeros or something. Otherwise, I don't know where you intend to get the rest of the data.
