I would like to combine 2 columns together with a , in between the columns. for example column 1 has 0% and column 2 has 1.0 and the final result should be 0%,1.0.

A={'0%';'1%';'2%'}
B={'1.0';'2.0';'3.0'}
out=strcat(A,B)
If your data are different from what I posted, then clarify your question

column 1 is a cell array but column 2 is a double.

A={'0%';'1%';'2%'}
B=[1;2;3]
C=arrayfun(@(x) sprintf(',%.1f',x),B,'un',0)
out=strcat(A,C)

You'll have to do this w/ a specific format...
>> fprintf('%d%%,%.1f\n',x')
0%,1.0
>>
While I used a 2-element vector, NB that you'll have to transpose an array to write in row-major order for output.
