Arduino to Matlab - save data in vector / array

hey guys,
does know how store serial data coming matlab in array? new matlab , getting dimension error whenever enter code:

s = serial('com10');
fopen(s)

for = 1 : 1000,
  v(i) = fscanf(s);
end

fclose(s)
delete(s)
clear s

thanks

fscanf reads available data when call it, it's reading more 1 value @ time.  if type "doc fscanf" it'll show you can add arguments specify how many values read.  

assuming you're printing ascii characters arduino, looks want use fscanf(s, %d, 1) if you're reading integers, or fscanf(s,%f,1) if you're reading floats.

you v = horzcat(v, fscanf(s)), append data read fscanf() v.  you have make sure v has @ least 1 value before call horzcat, cant concatenate onto empty matrix.  and if fscanf returns data in columns instead of rows, might have use vertcat instead.
