Help,symbolic math,multivariable eqn

I really hope someone can help me with this one...
I need matlab to help me generate a really long eqation with several
terms. Two of the variables have known values stored in a matrix but
there are also 6 unknown variables. Once I get the equation entered, I am
going to run it through Optimization toolbox.
The equation goes something like this:
f=(y1-c1(exp(-a1*t1)-exp(-a2*t1))^2 + (y2-c1(exp(-a1*t2)-exp(-a2 *t2))^2 +
...
y and t are the known matrices, c1, a1, a2 are unknowns. Y and t increment
in each term and then the terms are summed together. There are 20 terms
total.
How do I enter the equation with matlab recognizing the unknowns and still
substituting the values from the matrices? Then how do I get it to sum
the terms?
Thank you!
