For two resistors in series (e.g., Ra and Rb), the equivalent resistance is Ra + Rb. For two resistors in parallel (e.g., Rc and Rd), the equivalent resistance is 1 / (1/Rc + 1/Rd). With this information and the figure in your question, you should be able to compute the equivalent resistance of the entire circuit.
Tip: Take it one step at a time -- start with R6 and R7.
If you get stuck, post your code and a follow-up question.

% You can use the following MATLAB function to perform your task.
% Here, take R = [R1, R2, R3, R4, R5, R6, R7]
function Req = equiv_res(R)
par = inline("1/(1/x + 1/y)");
Req = R(1) + par(R(2) + R(3), R(4) + par(R(5), R(6) + R(7)));
