can anyone help me to create an empty array to store a 11 x 3 string array.

I am rating a loop to store each value for every image. i have to loop i just can't create a suitable array to store the words and numbers. This is what each image gives out:

"Sky" "268032" "786432"

"Building" "0" "0"

"Pole" "131" "786432"

"Road" "734" "786432"

"Pavement" "7610" "786432"

"Tree" "7450" "786432"

"SignSymbol" "7082" "786432"

"Fence" "5490" "786432"

"Car" "6912" "786432"

"Pedestrian" "3669" "786432"

"Bicyclist" "9836" "786432"

Thanks.

what is this vairable 'm' you are using or 'j' and 'i'? im guessing the 'n' is n i have already declared but none of these other values have been declared.

They are just indices.

n and m are defined in my comment (".... for nxm empty cell array).

i and j are just indices. c(i,j) is the i_th row and the j_th column.

Why not set up a struct?

s = struct('a',{},'b',{},'c',{});%label the fields to whatever you want
for k=1:11
  s(k).a=%'Building' from picture
  s(k).b=%268032
  s(k).c=%786432
end
