i just want to assign the
m(0)=1;
m(1)=1;
m(2)=1;
and get the sum of them,but when i assign them,the matlab can't get the answer,and why?
syms s1;
syms m(k);
syms z(k);
m(0)=1;
m(1)=1;
m(2)=1;
s1=symsum(m(k),k,0,2)

Remember matlab index starts from 1...the index should be always positive.
m(0)=1;
m(1)=1;
m(2)=1;
The above is same as:
m = [1 1 1] ;
The above step is short, effective. You can access the elements using:
m(1)
m(2)
m(3)
MATLAB is very effificent and simple.

why? the below works because the right side should be a symbolic object to perform the operation you need
syms m(k)
m(k)=k
symsum(m(k),k,0,2)
