What were your previous attempts? Where are you stuck? Do you want others to do the work for you or do you want to learn something?

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)));
end
