Question

Must be solved in Matlab. Please show screenshots of all code and comments so I can learn.

Without defining a function in an m-script (think anonymous functions here!) and for the following function: f(x) 4x2-50x +5 a. Use the fplot function to plot the function between -10 and 10. Find the minimum of the function between -10 and 10. Give both the x-value and the function value at the minimum. Be sure you show the entire code for how you do this. b. c. Calculate the area under the curve from -10 to 10. Again, document your solution.

Explanation / Answer

Solution:

code:

a)

function Y = calcFun(x)
Y = 4 * x^2 -50 * x + 5 ;                      % save it as calcFun.m
end

% now

% in command prompt type

fal = @calcFun

fplot(fal,[-10, 10])

b)

% to get minima

fminbnd(fal,-10,10)
