problem in reading comma delimited data array

Hi,

I have to read comma delimited array data with nonuniform
rows,columns. I just needed to read these data into single array A.
I did like this:

A=dlmread(filename, ',' )

but this does not displays all data and introduces unwanted zeros.
What I need is just in the form of continous array.
A(1)=1157
A(2)=1088
....

A(n)=957

Could you please suggest how to accomplish this task?

1157,1088,1169,1169,984,1322,1178,1103,1211,1292,

1171,1133,
1227,1142,1216,1259,1299,1232,1117,1155,
1232,1083,1020,1394,1196,1148,1083,1189,1133,1034,
1157,1034,1097,1299,1157,1130,1155,1349,1232,1103,
1103,1083,1027,1166,1148,1250,1155,1047,1054,1018,
1189,1126,1250,1297,1178,1043,1103,1250,1272,1169,
1004,1083,1164,1124,1027,995,1169,1270,1011,1247,
1101,1004,1004,1065,1223,1184,1216,1180,1142,1277,
1206,1076,1076,1189,1121,1178,1031,1076,1178,1209,

1043,1043,1002,1152,1097,1034,1002,989,1092,1115,
1115,1047,1040,1038,1085,1126,1058,1067,1115,1263,
1124,1110,1097,1097,1157,1000,991,995,1013,1007,
971,971,980,993,1043,1097,982,971,971,1065,
1022,1029,989,1029,995,982,1090,980,971,957

One possibility:

data = fileread('nameOfMyDataFile.txt');
data(data==char(10)) = []; %get rid of newline characters
data(data==char(13)) = []; %get rid of carriage returns
data = str2num(data)'; % convert to a column of numeric data

You can use TEXTSCAN:

>> fid = fopen(filename);
>> d = textscan(fid, '%f', 'delimiter', ',');
>> d = d{1};
