It cannot work since
--> size(k)
ans =
300. 1.
--> length(i)*length(j)
ans =
90000.
i.e. NodesMatrix2(i,j+1) has 90000 elements and resu(k) has 300
S.

Dear all
I’ve a submatrix issue on the following example, and I do not remember
(or understand) why : how can I do this ?
(the goal is to extract and to store within a matrix results from an
Ascii file)
Thanks for any help
