index out of bounds
11 views (last 30 days)
Hi I'm trying to execute a program but I keep getting this error:
"Attempted to access indx(1); index out of bounds because numel(indx)=0"
I understand what it means, but I'm not able to fixe it, I need some help.
Here is the code with the error:
for i = 1:nel
for j = 1:nen
Thank you guys

Hamid - What is the data type of the numbers in Dof and Edof - integers or floats? If floats, then you will not be able to use find(check==0) and will have to use some sort of tolerance around the numbers to see which are close enough to zero i.e.
check = [1 1.2 0.00000003 3.2 -0.00000004 4 12 55]';
tol = 0.000001;
And then, check to see if anything is returned before accessing rowIdcs
(I renamed indx and dum to rowIdcs and colIdcs because that is what the two output parameters refer to - the row indices and the column indices of the elements of check that satisfy the criteria.)
In the above example, since check is a column vector (due to the transpose '), then rowIdcs will have the indices of the rows of check that satisfy the criteria
and those values are
But you need to be careful. If check happens to be a row vector, then you need to use colIdcs to access those elements in check. And...if check happens to be a matrix, then you will need to use both vectors, rowIdcs and colIdcs, to get the correct value from check.
