Help with the below question

x = -10:0.1:10;
y = [1 6 0.03 0.08 10]';
A = 23 * (atan((0.005 + y)./x.^2));
B = diff(A,1,2)/0.1;
plot(x(1:end-1),B')

How to get the maximum value in each of the obtained plots for the mentioned y values?

Answer 1

Hi @Amy Topaz

I think you can use the max() function.

max(B(1,:))
max(B(2,:))
max(B(3,:))
max(B(4,:))
max(B(5,:))

Answer 2

x = -10:0.1:10;
y = [1 6 0.03 0.08 10]';
A = 23 * (atan((0.005 + y)./x.^2));
B = diff(A,1,2)/0.1;
plot(x(1:end-1),B')

 [val, indx] = max(B,[],2);
 hold on
 for i=1:length(indx)
    plot(x(indx(i)),val(i),'d')
 end
