how can i seperate the value exp(1i*2*pi*bbbb);

x1=exp(1i*2*pi*bbbb);
d1=bb1.*exp(1i*2*pi*bbbb);
d2=abs(d1);
d3=angle(d1);
d4=exp(1i*d3);   %value are not same as x1 
%how can i extract the value of x1 from d1

Answer 1

[Adam Danz]

The question is unlcear.

Given d1 from [d1 = bb1 * exp(a)], are you asking how to get exp(a)? If so,

exp(a) = log(d1/bb1);

Answer 2

[aaru sri]

i want to find the value of x1 from the d1

Answer 3

[madhan ravi]

syms x1 bb1 d1
isolate(d1==bb1.*x1,x1)

Answer 4

[Bruno Luong]

"i want to find the value of x1 from the d1"

x1 = d1/abs(d1)

if bbbb is real.

You need a major update of complex number theory.

[aaru sri]

d1=bb1.*exp(1i*2*pi*bbbb);

d12=abs(d1);

d13=angle(d1);

d16=d13./(2*pi);

here i m getting the change in phase at few elements ...value of d16 is same as bbbb but few values are going negative how to correct it
