Concatenate an unknown amount of strings to a master string.

I am trying to figure out how to add multiple strings to a master string. I want the end result to be a long string of binary numbers so I can parse into a cell array.

addingString = 1001
addingString = 1011
addingString = 1101
addingString = 1111
addingString = 1001
addingString = 0011
addingString = 1000
.
.
.

At the end of the loop the finalString should have all the contents inside:

finalString = 1001101111011111100100111000...

I tried different variations of concatenating strings/arrays and preallocated the size but nothing seemed to work.

Here is an excerpt of code:

while (data >= info)
    finalString = [];  
    finalString = strcat(finalString, AddingString)  
end

finalString

What are the variable types? Is addingString a string, a char vector, a double? What you show above is a double, but it is not clear if this is actually what you have in your real code.

AddingString is a char

The first thing you are doing in your while loop is setting the finalString to [] - so you lose everything you concatenate together on every loop iteration. finalString=[] needs to be set before you enter the loop.

Easy enough. Thanks for your help.
