Solve with Matlab. Please type code clearly.

The thermal efficiency of a straight rectangular finned surface is given by eta_fin = tan h mL_c/mL_c Where m is the fin parameter and L_c is the length of the fin plus twice the thickness. For a fin with a 80% efficiency, a thickness of 1mm and m=0.1 mm-1, determine the length of the fin within 4 significant digits of accuracy. Solve using the secant method and initial guesses of LC_0 = 10 and Lc_1 = 20. Set the maximum number of iterations to 30 Include a break statement or use a while loop so when the solution reaches the specified accuracy it will stop
