Undefined function 'savetofile' for input arguments of type 'sym

2 views (last 30 days)
Hi all,
I'm using a co-author's program from a published paper and while running his code with different data, I ran into the following error message:
Error using runDLRsym (line 40)
The source code (C:\Users\nkhoz\Desktop\Wed10Aug\ReplicationFiles_Empirical\BenchmarkModel\PrepWald\runDLRsym.m) for the parfor-loop that is
trying to execute on the worker could not be found.
Error in RunPrep (line 6)
runDLRsym(nv, ng);
Caused by:
Undefined function 'savetofile' for input arguments of type 'sym'.
Error using remoteParallelFunction (line 84)
Worker unable to find file.
Undefined function 'savetofile' for input arguments of type 'sym'.
After I asked him about it, he ran the program and the he got the same error message back (this program used to work just fine). Neither of us has any idea. I was hoping someone would be kind enough to help me work this out? Apparently SaveToFIle was introduced in 2015, but I'm not aware/cannot find any info of it being replaced by something else. I do have the symbolic toolkit add on, so that's not the issue.
For the sake of clarity, here are the lines that Matlab isn't happy with. Line 40 is from this:
function runDLRsym(nv, ng)
...
...
...
...
for row = 1:nv
parfor col = 1:ng-1
name = sprintf('DLRsym%d%d',row,col);
varr = DLRsym(row,col);
savetofile(varr,name);
end
end
toc
Line 6 from the program that calls DLRsym is here:
tic
%parpool(4)
nv= 6;
ng = 3;
runDLRsym(nv, ng);
toc
getjacobDLR(nv, ng);
toc
%4000 seconds to run

Hi Benjamin, thanks for your message. I haven't written any parts of this program myself, so I'm a bit in the dark-do you mean that the author(s) had programmed their own function called savetofile and that is the bit that might be missing?
