Hello, I wanted to save a data file that contains different array sizes. Can you assist me with this task? This is the code that I have so far:

a = (0.5)*rand(15,1);
b = (0.5)*rand(15,1);
c = (0.5)*rand(20,1);
d = (0.5)*rand(20,1);
e = (0.5)*rand(20,1);
A = [a b c d e];
fileID = fopen('check.txt','w');
fprintf(fileID,'%6s %6s %6s %6s %6s\r\n','a','b', 'c', 'd', 'e');
fprintf(fileID,'%6.5f %6.5f %6.5f %6.5f %6.5f\r\n',A');
fclose(fileID);

What should be written in lines 16 to 20, where you do not have values for a and b? Should there be zeros for a and b, or should there be only three values c, d, e, or what do you want?

When you execute A = [a b c d e]; don't you get an error? The dimensions of a, b, c, d & e aren't consistent. You cannot concatenate them. Try using cell. Each cell can contain any type of data. Or just write them separately into files.
