Hello,
In the code below, how do I go about saving the cell data to a csv file with the specified headers?
Here is my code:
clc;clear;
A = 1:15;
B = (0.5)*rand(15,1);
C = 1:20;;
D = (0.5)*rand(20,1);
E = (0.5)*rand(20,1);
CELL{1} = A';
CELL{2} = B;
CELL{3} = C';
CELL{4} = D;
CELL{5} = E;
% fileID = fopen('check.dat','w');
% fprintf(fileID,'%6s %6s %6s %6s %6s\r\n','Iter1','b', 'Iter2', 'd', 'e');
% fprintf(fileID,'%6.5f %6.5f %6.5f %6.5f %6.5f\r\n',CELL);
% fclose(fileID);

What results are you expecting? Your CELL{1} and CELL{2} will be 15 x 1, but your other CELL entries are 20 x 1 . Do you want empty entries for the first two columns for the last 5 rows?

I wanted to have the last entries empty in the first two columns. Thanks.

Create a cell array large enough to hold everything if everything was the same length -- so in this case, 20 by 5. Set all the entries to '' the empty string. Now in the entries that should have a defined value, write in the string corresponding to the number that goes in that position. For example,
Astr = cellstr(num2str(A.', '%6.5f'));
Output(1:length(Astr), 1) = Astr;
Once the entire Output cell array has been populated,
fmt = '%s,%s,%s,%s,%s\n';
OutTranspose = Output .'; %need to transpose it
fprintf(fileID, fmt, OutTranspose{:});
The transpose has to do with row versus column concerns.

Try this:
clc; % Clear the command window.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
A = 1:15;
B = (0.5)*rand(15,1);
C = 1:20;;
D = (0.5)*rand(20,1);
E = (0.5)*rand(20,1);
CELL{1} = A';
CELL{2} = B;
CELL{3} = C';
CELL{4} = D;
CELL{5} = E;
fileID = fopen('check.dat','wt');
fprintf(fileID,'%6s, %6s, %6s, %6s, %6s\n','Iter1','b', 'Iter2', 'd', 'e');
fprintf(fileID,'%6.5f, %6.5f, %6.5f, %6.5f, %6.5f\n',CELL{1});
fprintf(fileID,'%6.5f, %6.5f, %6.5f, %6.5f, %6.5f\n',CELL{2});
fprintf(fileID,'%6.5f, %6.5f, %6.5f, %6.5f, %6.5f\n',CELL{3});
fprintf(fileID,'%6.5f, %6.5f, %6.5f, %6.5f, %6.5f\n',CELL{4});
fprintf(fileID,'%6.5f, %6.5f, %6.5f, %6.5f, %6.5f\n',CELL{5});
fclose(fileID);

Thank you. However, how do I keep then the last 5 entries empty in the first two columns to match up the other columns? Your solution is still skewing the saved data set. Thank You.

Either see if Walter's solution works, or give an example of what you want to the output, because I don't know what it means to have the last 5 entries empty in the first two columns.

Hello, this is the output I would like to get...
Iter1 b Iter2 d e f
1, .05120, 1, .8512, .5656, 5632
2, .56355, 2, .5635, .1259, .6321
...
15, .1256, 15, .8632, .4425, .0856
16, .2265, .4863, .9652
...
20, .1125, .9965, .1256
Thank you for your time.

Is your goal to have column-oriented output, or is your goal to have a csv file? Because a csv file would look like
"Iter1","b","Iter2","d","e","f"
1,.05120,1,.8512,.5656,5632
2,.56355,2,.5635,.1259,.6321
...
15,.1256,15,.8632,.4425,.0856
,,16,.2265,.4863,.9652
...
,,20,.1125,.9965,.1256
