Function for writing to files isn't working properly when I call it.

I wrote a function to write values from three arrays into a .txt file.

function errorCalc(Array1,Array2,Array3)
A=[Array1;Array2;Array3];
fileID = fopen('Exact.txt','w');
fprintf(fileID,'%6s %12s %18s\n','t','a(t)','h(t)');
fprintf(fileID,'%6.2f %12.8f %18f\n',A);
fclose(fileID);

This function runs fine whenever I run it by itself, but whenever I call it in another function:

errorCalc(t_val,a_val,h_val)

It does nothing. When I look at the file in question, it's the same as when I ran errorCalc by itself. It's not writing the values of the arrays into the file.

Check to be sure that you are in the same directory. You are writing to the current directory but that might be changing.

errorCalc, the function i'm calling it in, and Exact.txt are all in the same folder. Is this what you mean?

Time to use the debugger to examine the values being written.
