I have 3 columns of data(3X1) saved in CA, TX, FL variables:

 CA = [1;2;3]
 TX = [4;5;6]
 FL = [7;8;9]

I want to generate an output to a* text file* as seen below:

 CA TX FL
4  7
5  8
6  9

I have been working with various ways fprintf and etc, but the rows and columns are not lining up. Here is one idea that I have been working with:

Thanks, Amanda

It wasn't clear to me if you wanted to include the state abbreviations as headers to the columns, so I included a flag that you set true/false.

There are probably slicker ways to do this, but I tried to stick close to the format you had, to help your understanding.

INCLUDE_HEADER = true;
CA = [1;2;3]
TX = [4;5;6]
FL = [7;8;9]
myMatrix = [CA,TX,FL];
mycell = num2cell(myMatrix);
myHeader = {'CA','TX','FL'};
[nrows,ncols] = size(mycell)
filename = 'celldata.txt'
fid = fopen(filename,'w')
if INCLUDE_HEADER
  fprintf(fid,'%s %s %s\n', myHeader{:});
end    
for row=1:nrows
  fprintf(fid,'%d %d %d\n', mycell{row,:});
end
fclose(fid)
