need matlab published solution please

It is well known that the yield strength of metals is dependent on the size of the poly-crystals that make up the microstructure. The yield strength, sigma, can be related to the average grain diameter by the Hall-Petch equation: sigma = sigma_o + Kd^-1/2 where sigma_o and K are material-specific constants and d is the average grain size. Create a function called HallPetch. The function should take 3 scalar inputs (sigma_o, K, d) which it then uses to calculate the yield strength. Make a table of yield strengths for grain sizes going from 0.1 to 10 mm in 0.1 mm increments. Your function should not take a vector input. Use a loop to call the function multiple times. Take sigma_o = 12,0000 psi and K = 9600 psi Squareroot mm. The table should have the following form: Your answer below should first include a cut-and-paste of the "published" function file and then the cut-and-paste of the "published" main file and its output
