Ex4-5: Mesh and plot a surface Write a function named ex4p5. It received two vector variables and returns three matrices. Write a subfunction that implements the "three-hump camel" function: f(x, y) = 2x\textsuperscript{2} - 1.05x\textsuperscript{4} + \frac{x\textsuperscript{6}}{6} + xy + y\textsuperscript{2} Write your subfunction in such a way that it accepts "vectorized" input (i.e. it computes function values elementwise when x and y values). Your main function receives to variables which contain the ranges of x and y, i.e. [X\textsubscript{min}, X\textsubscript{max}] and [Y\textsubscript{min}, Y\textsubscript{max}]. Your main function returns as output values three 10x10 matrices, which contain the x, y coordinate combinations (use the "meshgrid" function, two first values) and the corresponding z = f(x, y) values (as the third function value). Draw the function surface using the function "surf". Give your figure a title and label the axes. Note that the Moodle interface does not display figures - use Matlab to see what you've drawn. (To see the "humps" you need more points than ten points in each direction and probably also a logarithmic z-axis.) (Food for thought - do not return: How you could change your function so that if one of the coordinate ranges would be just a scalar, it would draw a 2D line? Or if both coordinate ranges were scalars, function would return just the function value with the given pair of coordinates?)

Two autosomal genes control horn color in dragons. Pure-breeding gold-horned dragons were mated to pure-breeding silver-horned dragons. All of the F1 were gold. The F1 were intermated and the F2 generation consisted of 146 gold, 16 silver and 96 bronze. Choose the genetically based phenotypic ratio that should be hypothesized to explain the F2 data. ? 9:3:3:1 ? 9:3:4 ? 12:3:1 ? 9:7 ? 15:1 ? 9:6:1 ? 13:3
