Output variables and text to .txt file

I am trying to output text and their related variables to a .txt file. I want the file to look like:

Mean   = XXX.YY
Median = XXX.YY
Mode   = XXX.YY
Var    = XXX.YY
Stdev  = XXX.YY
Min    = XXX.YY
Max    = XXX.YY
Count  = XXXXXX

With all except count to have 2 decimal places, the equal signs to be vertically aligned, and the decimal points to be vertically aligned. I do not have the formatting down, and I thought I had the output file script written correctly. Here is what I have:

x_count = 32;
x_max = 150;
x_mean = 36.7500;
x_median = 18.5000;
x_min = 0;
x_mode = [4,7,8,15];
x_std = 39.4018;
x_var = 1.5525e+03;
C = cell(8,2);
C{1,1} = 'Mean=';
C{1,2} = x_mean;
C{2,1} = 'Median=';
C{2,2} = x_median;
C{3,1} = 'Mode=';
C{3,2} = x_mode;
C{4,1} = 'Var=';
C{4,2} = x_var;
C{5,1} = 'Stdev=';
C{5,2} = x_std;
C{6,1} = 'Min=';
C{6,2} = x_min;
C{7,1} = 'Max=';
C{7,2} = x_max;
C{8,1} = 'Count=';
C{8,2} = x_count;

fileID = fopen('exp.txt','w');

fprintf(fileID,'%6.2f %12.8f\r\n',C);
fclose(fileID);

type exp.txt

I'm using a cell to basically have an array with both text and numbers, but the function to print these doesn't work with cells, so now I'm assuming I need an entirely new way to do this. If it is more efficient and possible to align the equal signs and decimal points, all the better.

[per isakson]

• Matlab is column major, i.e. the columns of C are printed one after another.
• x_mode is a vector and thus doesn't match the format specifier
• "... 2 decimal places ..." &nbsp but you have specified eight
• It is easier to print this data to a file using a for-loop

I found the printing code specifically on another page on this website. I wasn't really sure of what every parameter meant, and was hoping someone could explain them. It was literally just a copy-paste that I was hoping to figure out along the way.

Hi, take a look at this from the file exchange

https://www.mathworks.com/matlabcentral/fileexchange/25387-write-cell-array-to-text-file

so to write to the cell array to text file you would give the filename and the cell to write as arguments so:

 dmlcell('exp.txt',C);
