Suppose x=2 and y=5.
𝑧 = [ 4 1
2 3
1 7 ],
𝑚 = [ 4 5 3
5 1 7
1 3 6 ],
𝑛 = [ 3 3 5
2 6 4
1 9 1 ]
Use MATLAB command to compute the following: 𝑥𝑦^4/𝑥^2 , 𝑥𝑦^3 − 𝑥^2/𝑥^3 −1 , 𝑚 × 𝑧, sin(𝑚) , 𝑚 × 𝑛 (𝑐𝑜𝑚𝑝𝑜𝑛𝑒𝑛𝑡𝑤𝑖𝑠𝑒 𝑜𝑟 𝑒𝑙𝑒𝑚𝑒𝑛𝑡 𝑏𝑦 𝑒𝑙𝑒𝑚𝑒𝑛𝑡)

𝑥𝑦^4/𝑥^2 : x*y^4/x^2
𝑥𝑦^3 − 𝑥^2/𝑥^3 −1: similar to above
𝑚 × 𝑧: m*z
sin(𝑚): You guess?
𝑚 × 𝑛 (𝑐𝑜𝑚𝑝𝑜𝑛𝑒𝑛𝑡𝑤𝑖𝑠𝑒 𝑜𝑟 𝑒𝑙𝑒𝑚𝑒𝑛𝑡 𝑏𝑦 𝑒𝑙𝑒𝑚𝑒𝑛𝑡): m.*n
