1. Filename: MAE1090_Lab9_1.nm Write an m-file to evaluate the following function of two variables z 10 sin(x + sin(y) over the range of -10 sx s 10 rad and -10 s y S 10 rad using 100 points in each direction. Use meshgrid.m to generate x and y matrices, with which you can calculate the matrix z with a single MATLAB command. Plot the resulting z matrix as a surface plot and then as a contour plot.
