Subscript indices must either blabla

>> gamma=0;
>> s=0;
>> dx=linspace(0,10);
>> dx=0.1;
>> xv=linspace(0,10);
>> f=@(x) sin(2*pi*x/10);
>> xnodes=(0:0.1:10-0.1);
>> f=adr_per_cen_fd(0,f(xnodes),u,ni,gamma,s,xnodes,dx);

SUBSCRIPT INDICES MUST BE POSITIVE OR REAL, UHM. can you help me?

Thank you

What is ‘adr_per_cen_fd’?

What is adr_per_cen_fd? It thinks it is an array, not a function and if its an array, all the dimensional indexes must be integers. You can't have the 0.1th column of a matrix.
