A= {<1x1 cell> <1x3 cell> [4,0] <1x4 cell>}
where
<1x1>= [2,3,4]
<1x3>= [ ] [3,4] [3,8,13]
<1x4>= [9,4] [9,8,13] [ ] [9,14,19]
so i want my answer to be in form of a single array of cells as below,
B={ [2,3,4] [3,4] [3,8,13] [4] [9,4] [9,8,13] [9,14,19] }

OK I see that you want null cells to be left out, but how did cell number 4 come to contain [4]:
B={ [2,3,4] [3,4] [3,8,13] [4] [9,4] [9,8,13] [9,14,19] }
The third cell of A contains a vector [4, 0]. But B{4} is [4]. What happened to the 0? Do you want to exclude zeros also for some reason?

A = {{[2,3,4]},{ [],[3,4],[3,8,13]},{[4,0]},{[9,4],[9,8,13],[],[9,14,19]}}
A = 1×4 cell array
{1×1 cell} {1×3 cell} {1×1 cell} {1×4 cell}
B = [A{:}]
B = 1×9 cell array
{[2 3 4]} {0×0 double} {[3 4]} {[3 8 13]} {[4 0]} {[9 4]} {[9 8 13]} {0×0 double} {[9 14 19]}

Or without the anonymous function:
B(cellfun(@isempty,B)) = [];
"...so i want my answer to be in single cell array"
and is what my answer gives you.
