Write a computer program using MATLAB to calculate the unit cell volume in the units of A and nm3. Your program should prompt the user to input the (a) type of unit cell, (b) necessary lattice constants, and (c) angles. The program then should recognize the inputs made and use the appropriate formula for the calculation of unit cell volume. Use any programmer language. Write a computer program using MATLAB that will ask the user to input the atomic mass, atomic radius, and cubic crystal structure for an element. The program output should be the packing fraction and the theoretical density. Use any programmer language
