Please help me with this assignment!!
"Create a file called data1 by using the Matlab editor. For instance,
23
56
18
6
7
43
Write a Matlab script that reads data1, calculates the sum of its records sum1, and writes sum1 to the file called result."
Here is what I have so far, I am stuck on finding the sum and writing the sum into a file.
data1.m:
clc,clear
x = [23 56 18 6 7 43];
fid = fopen('rabFile.txt','w');
fprintf(fid,'%5.2g\n',x);
fclose(fid);
assignment_19.m:
fid = fopen('rabFile.txt','r');
if fid == -2
disp('Error opening file');
else
arr = fscanf(fid,'%g',[1 Inf]);
end
fclose(fid);
rabFile.txt:
23
56
18
6
7
43

you should be testing fid less than 0 rather than equal -2 by the way.

You are writing data to a file in that first part of your code, so you know how to write data to a file.
If you search on Google for 'calculate sum Matlab' I expect the function you need will be the top result.
