Question

let z be a complex matrix like [i -1 -2 -3]

Answer 1

when i plot this in Matlab it returns

Answer 2

but i expect this

Answer 3

@UnkleRhaukus

Answer 4

let me try

Answer 5

sure...thank u for coming

Answer 6

what are you entering ,

when i enter this i get the expected plot
z=[i,-1,-2,-3];plot(z,'o')

Answer 7

oh yeah my bad...how about this one [-1 -2 -3] ?

Answer 8

i mean when we have a matrix with real components...how plot it like complexs ???

Answer 9

im not sure what you mean

Answer 10

i mean i expect this when entering z=[i,-1,-2,-3];plot(z,'o')

Answer 11

sorry z=[-1,-2,-3];plot(z,'o')

Answer 12

i am still confused

Answer 13

its ok Unkle...

K=linspace(0,5,2000);
p=1;
for i=1:length(K)
b=roots([1 6 11 6+6*K(i)]);
c(p)=b(1);
c(p+1)=b(2);
c(p+2)=b(3);
p=p+3;
end
for k=0:1999
x1(k+1)=c(3*k+1)+0*sqrt(-1);
y1(k+1)=0;
x2(k+1)=c(3*k+2)+0*sqrt(-1);
x3(k+1)=c(3*k+3)+0*sqrt(-1);
end
plot(x1,y1,'o')
hold on
plot(x2,'o')
hold on
plot(x3,'o')
axis([-4 1 -3 3])

Answer 14

i defined a zero matrix y1 and fixed it
