v=[1 500 900 1200]; 
 % ^--appended 1 at the beginning
Splittable=cell(numel(v)-1,1);
for k=2:numel(v)
    Splittable{k-1}=T(v(k-1):v(k)-1,:);
end
Splittable{k}=T(v(end):end,:) % where T is your table

MATLAB: How to split data text file with unequal elements in the row into several files

With just one textscan call. The test file is attached (you did not provide us with a sample file).

opt = {'CollectOutput',true};
[fid,msg] = fopen('test.txt','rt');
assert(fid>=3,msg)
C = textscan(fid,'%f%f%f%f%f',opt{:});
fclose(fid);
M = C{1};
D = diff([isnan(M(:,5));false]);
E = find(D<0);
B = find(D>0);
for k = 1:numel(B)
    F = sprintf('new %d.csv',M(B(k),5));
    csvwrite(F,M(B(k):E(k),1:4))
end
