How I use quiver to plot 3+2i
Just use: quiver(3,2,1) for any complex number c, use: quiver(real(c),imag(c),1)

Array slice indexing?
Take for example: a=[1 2 3; 5 6 7; 8 9 12] and i=2 then a(i,end:-1:1) gives: the 2nd row in right to left order (the eleme...

Write a program that calculates the length of hypotenuse c for all (!) combinations of legs a and b and do so using a for loop!
An other way without loop a = [3;5;1;3;2]; b = [1;3;2;7;2]; [A B]=meshgrid(a,b); C=[A(:),B(:)]; c=sqrt(C(:,1).^2+C(:,2).^2)...

Bisection method relative error
Hi Just use "while" loop with your condition as follows: f=@(x) log(x)-cos(x)-exp(-x); x1=1; x2=2; xmid=(x1+x2)/2; while (...
