Hello ,

I have this matrix as a result of code :

1,85506173843200 1,00229272121327

1,74935758533076 1,00727718522748

1,54993783446447 1,02899346511808

1,18399896863203 1,18885602705206

and i want to create a txt file named as activity_coefficients.txt which will contain the above matrix as it is.

i use these commands

fileID=fopen('activity_coefficients.txt','w')

fprintf(fileID,'%f\n',gamma)

but the txt file have the above matrix elements one after another.

Can anyone help me ?

Thanks in advance

Try this:

gamma =[1.85506173843200,	1.00229272121327;
        1.74935758533076,	1.00727718522748;
        1.54993783446447,	1.02899346511808;
        1.18399896863203,	1.18885602705206];
    
fID = fopen('activity_coefficients.txt','w');
fprintf(fID,'%16.14g %16.14g \r\n',gamma');
fclose(fID);
