Create output file in matlab containing numeric and string cells - r

Question

I am currently working on a project where I have to program the same tool both in Matlab and R and compare both software options.
I started in R and now I am translating the code to Matlab but I am now stuck at the most important part. The output file that the tool creates after doing the analysis.
Basically, my tool makes an analysis that loops n times, and after each loop I get many variables that go into an output table. So, to be more clear, after each loop I get variables:
A = 123
B = 456
C = 'string1'
D = 'string2'
E = 789
The values in each variable change after each loop, I just want to make clear that the variables are both numeric and string values since this is what causes my problem.
In R what I do after each loop is:
outp <- cbind(A,B,C,D,E)
and create a data frame containing each variable in one cell arranged horizontally to afterwards add the result of each loop vertically in a new data frame:
outp2 <- rbind(outp2,outp)
so in the end I get a data frame (outp2) with A,B,C,D,E columns and n rows containing the values of each variable after each loop. So at the end of the looping process I can use write.csv function and create an output file of outp2 that contains both numeric and string columns.
I tried to do this in Matlab but I cannot find a function that can join the data in the same way I am doing it in R because using brackets '[]' only allows me to join numeric kind of variables. So basically my question is: How can I replicate what I am doing in R in Matlab?
I hope I was clear enough, I found it a bit hard to explain.

Answer 1

You can append your output with a cell array, first using curly brackets to declare your cell format (empty {} or containing your data {...}), then using brackets [...] to concatenate the output (one line after the others using ;).
out_array = {}; %initialize empty
%vertical concatenation with ";"
for ii = 1:3
out_array = [out_array; {123, 456, 'string1', 'string2', 789}];
end
This gives
out_array =
[123] [456] 'string1' 'string2' [789]
[123] [456] 'string1' 'string2' [789]
[123] [456] 'string1' 'string2' [789]

Answer 2

Don't now if this solves your problem, but in Matlab you can do things like
oupt = {123, 456, 'string1', 'string2', 789}
Just use curly braces instead of square brackets.

Answer 3

As they have said before, use curly braces to create a cell array. I imagine A, B, C, D, and E are your table headers and you already have the data that goes under them, so I'd do it like this:
outp = { A , B , C , D , E };
# This next step is only to have some data...
outp2 = magic(5);
outp2 = num2cell(outp2);
output = [ outp ; outp2 ]
output =
[123] [456] 'string1' 'string2' [789]
[ 17] [ 24] [ 1] [ 8] [ 15]
[ 23] [ 5] [ 7] [ 14] [ 16]
[ 4] [ 6] [ 13] [ 20] [ 22]
[ 10] [ 12] [ 19] [ 21] [ 3]
[ 11] [ 18] [ 25] [ 2] [ 9]
