a question of assigning the list elements

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)

Answer 1

[KSSV]

m = [1 1 1] ;
iwant = sum(m) ;

is there a way that we could use the form

m(0)=1;
m(1)=1;
m(2)=1;

oter than assign it in the matrix?

this form is convenient for the postprocess

[KSSV]

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.

Answer 2

[madhan ravi]

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)
