How can I read text file data separately row by row into different array

Hi, everyone. If the text tile data is shown as below:

13,7,8,4,9

3,21,5,3,7

4,6,87,35,7

45,2,5

I would like to read the text file into different array like a=[13 7 8 4 9], b=[3 21 5 3 7;4 6 87 35 7] and c=[45 2 5]. Is there any code to solve this problem? Thank you for reading my question.

Refer to importdata & str2num. Create a for loop based on the number of lines in the text file.

The following code might help you:

filename = 'textFile.txt';
delimiterIn = '\n';
Data = importdata(filename,delimiterIn);

a = str2num(Data{1})
b = [str2num(Data{2});str2num(Data{3})]
c = str2num(Data{4})

Or

filename = 'textFile.txt';
delimiterIn = ',';
Data = importdata(filename,delimiterIn);

a = Data(1,:)
b = Data(2:3,:)
c = Data(4,:)
c = c(~isnan(c))

The textFile.txt has the following data:

13,7,8,4,9

3,21,5,3,7

4,6,87,35,7

45,2,5
