How to use an output from on file as input in another file.

The given file "enzymeGeneral.m" generates a vector. " test-modified.m" generates a Jacobian.
How can I use these answers and sum them up as follows:

and

Here I try with
function [r,g] = enzymeGeneral(k)
[r]=enzymeLeastSquares(result,grad_all);
[g]=test_modified(result,grad_all);
S=sum(r,8)
V=sum(g,8)
Where "result" is supposed to call for the answer from the respective m. file.
But this doesn't work, since S and V do not call on the answers from enzymeLeastSquares.m and test_modified.m in order to sum them as given in S and V:
How can I use the answers from enzymeLeastSquares.m and test_modified.m as inputs for S and V in summation?
Thanks

"enzymeGeneral.m" doesn't creat a vector but an error:
>> enzymeGeneral
Unrecognized function or variable 'result'.
Error in enzymeGeneral (line 2)
[r,g]=enzymeLeastSquares(result,grad_all);
Hence, you should rework your scripts.

Do you mean something like this:
function [S,V]=enzymeLeastSquares(r,g);
S=sum(r,8)
V=sum(g,8)
and the calling function might look like this:
function [S,V] = enzymeLeastSquares(k)
N = 4; % number of experiments
result = zeros(2*N,1); % pre-allocate result arrays
grad_all = zeros(2*N,2);
dt=0.01;
T=1;
%k=[5;1];
y0_all = [2 1 1 4; 1 1 0 1];
y1_all = [1.0 0.5 0.3 2.4; 2.1 1.6 0.9 2.7];
for ii = 1:N
y0 = y0_all(:,ii);
y1 = y1_all(:,ii);
[SP,grad]=enzyme(y0,k,dt,T);
result((ii-1)*2+[1 2]) = y1-SP;
grad_all((ii-1)*2+[1 2],:) = -grad;
end
[S,V] = enzymeGeneral(grad_all, result)
But I haven't tested this jet. It shows only how to pass prameters onto a function and get results back.

Maybe this:
function [result,grad_all] = enzymeLeastSquares(k)
N = 4; % number of experiments
result = zeros(2*N,1); % pre-allocate result arrays
grad_all = zeros(2*N,2);
dt=0.01;
T=1;
%k=[5;1];
y0_all = [2 1 1 4; 1 1 0 1];
y1_all = [1.0 0.5 0.3 2.4; 2.1 1.6 0.9 2.7];
for ii = 1:N
y0 = y0_all(:,ii);
y1 = y1_all(:,ii);
[SP,grad]=enzyme(y0,k,dt,T);
result((ii-1)*2+[1 2]) = y1-SP;
grad_all((ii-1)*2+[1 2],:) = -grad;
end
result = sum(result);
