loading a two dimensional data from a file

how to upload data from a file of 2 dimensional with columns varying for each row using matlab.yhe variables are floating points.so if i am storing it in cell array even . and space between two values is occupying memory.wastage of memory

question is not clear. Do you want to load a two dimensional data from a file(xls) to matlab?

[Walter Roberson]

The values that are not present: are they only missing at the ends of lines, or can they be missing in the middle of lines?

Is there fixed maximum number of columns per line?

Is there a value (such as 0 or NaN) that can never occur in your data?

[annamaneni sriharsha]

no there is no fixed maximum number of columns per line.there are no o and NaN in the data and regarding values that are not present i didnt understand the question

@akshat i want to upload two dimensional as it is from any kind of file.in the file tha data is stored as

10.53 10.00 11.20 11.222 11.222 11.245
10.53 10.00 11.20 11.222 11.222 
10.53 10.00 11.20 11.222 11.222 
10.53 10.00 11.20 11.222 11.222 11.245
10.53 10.00 11.20 11.222 11.222 11.245
10.53 10.00 11.20 11.222 11.222 11.245
10.53 10.00 11.20 11.222

so how to upload as it is the data so that i can implement algorithms on the data

indata = {};

while true
  linein = fgetl(fid);
  if ~ischar(linein); break; end
  indata{end+1} = sscanf(linein, '%g');
end

i am getting a single dimension array not a two dimensional array
