Hi, i got the same issue.
I have 3 matrix. the first one is for data vector in matrix [1 2 3 12 11 6 7 8 9 10], the second is for the ii [1 2 3 3 3 7 7 8 9 10] and the last matrix is for the jj (column) [10 2 3 6 8 1 7 3 9 6]
when i creat my function and launch a test with this approach it is work properly... well at least... SOMEONE COULD HELP ME?
afficheMatriceCreuse([1 2 3 12 11 6 7 8 9 10], [1 2 3 3 3 7 7 8 9 10],[10 2 3 6 8 1 7 3 9 6])
i got this error message:
(1,10) 1
(2,2) 2
(3,3) 3
(3,6) 12
(3,8) 11
(7,1) 6
(7,7) 7
(8,3) 8
(9,9) 9
(10,6) 10
Index exceeds matrix dimensions.
Error in afficheMatriceCreuse (line 31)
fprintf('(%i,%i) %i \n', iM(ii),jM(ii),vM(ii))
or Index exceeds matrix dimensions.
Error in afficheMatriceCreuse (line 26)
iM(ii);
Function:
function afficheMatriceCreuse(vM,iM,jM)
for ii = 1:(numel(iM,jM,vM))
(line26) iM(ii);
jM(ii);
vM(ii);
(line31) fprintf('(%i,%i) %i \n', iM(ii),jM(ii),vM(ii))
end
end

for ii = 1:(numel(iM,jM,vM))
numel with multiple arguments has undocumented results. It looks to me as if it returns the product of the number of elements of the arguments after the first.
>> numel(1:50,[3 4 5],[3 4; 5 3])
ans =
12
That is, size and content of the first argument was ignored, and the number of elements of the second argument (3) was multipled by the number of elements of the third argument (4) to get the result.
