How to fill the remaining "N" number of rows, of an already populated vector, with zeros
60 views (last 30 days)
It may be confusing, so let me explain. The "GV" data I provided has values in it. It is size (18,001 x 1). I want the to fill the remaining "N" number of rows with zeros. So it may be a (20,000 x 1) or perhaps a (30,000 x 1) vector, but still with the first 18,001 rows filled with the "GV" values. How to do this??
Thank you in advance!

Alternatively, and perhaps more efficient depending upon how GV is generated/obtained...
GV(Ntotal,1)=0; % preallocate (could also write zeros(Ntotal,1) )
GV(1:N)=GVcalculation(1:N); % put the calculation results in first N locations
Which way is more effective depends on the details we don't know...
