I have a cell array with values like this
...
9 [10370;10371;10372]
10 [12933;12934]
11 10001
12 11320
13 [11347;11348]
14 [10362;10363]
17 [12632;12633]
...
And i want to add blank rows for all the missing numbers in the first collumn so it would look like this
...
9 [10370;10371;10372]
10 [12933;12934]
11 10001
12 11320
13 [11347;11348]
14 [10362;10363]
15
16
17 [12632;12633]
...
I have a list of how many items should appear on the first row but i'm having problems finding a way without using a for loop, the list is too big for that.

Ran in:
Will this work?
m = {...
9 [10370;10371;10372]
10 [12933;12934]
11 10001
12 11320
13 [11347;11348]
14 [10362;10363]
17 [12632;12633]};
inds = cell2mat(m(:,1));
lastRow = 20;
M = cell(lastRow,2);
M(inds,2) = m(:,2);
M(inds,1) = m(:,1)
M = 20×2 cell array
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {[ 9]} {3×1 double} {[ 10]} {2×1 double} {[ 11]} {[ 10001]} {[ 12]} {[ 11320]} {[ 13]} {2×1 double} {[ 14]} {2×1 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
