Hello, I'm having some issues with my disp function in my while loop. I'm trying to display my values accordingly to the disp function underneath my if statement, where I show how the according values change through each iteration of the while loop. I think the way I coded it is making it so that it adds all the values together rather than displaying the functions in separate columns. Could I have some help with this?
n = 2;
m = 1;
f = @(x) (0.4*sin(2*pi*x.^n)).*(exp(x.^m))-1
f = function_handle with value:
@(x)(0.4*sin(2*pi*x.^n)).*(exp(x.^m))-1
a = 1.85; %Boundary 1
b = 1.86; %Boundary 2
err = 1; %Had to assign error a random value just so that it exists
counter = 0; %Keeps track of the iterations
if f(a)*f(b)<0 %Product of f(a) and f(b) guarantees a root between the boundaries
disp("itn dx xmin xmax f(xmin) f(xmax) xmid f(xmid)")
while err > 0.000001 %The while loop will keep looping until our error dips below 10^-6
t = (a+b)/2; %t will be our midpoint
if f(t)*f(a)<0 %If the product of f(t) and f(a) is negative, we make b equal to t
b = t;
elseif f(t)*f(b)<0 %if the product of f(b) and f(t) is negative, we make a equal to t
a = t;
end
counter = counter + 1; %Updates each time we go through the while loop
disp([num2str(counter) num2str(b-a) num2str(a) num2str(b) num2str(f(a)) num2str(f(b)) num2str(t) num2str(f(t))])
err = abs(b-a); %Absolute value prevents negative values from ending the while loop
end
end
itn dx xmin xmax f(xmin) f(xmax) xmid f(xmid)

I expect you'd be much better off using sprintf to format your output.
