I have a exponential function and cordic exponential function.
I see a differenc in output for exponential and cordic exp func
Example -
theta = [-pi:pi/4:pi]
y = exp(theta)
y1 = cordiccexp(theta)
cordic exponential works only for complex number where as exponential works for complex and real/integer numbers
Question - How to (Mathematics) get cordiccexp out same as exponetial function

cordicexp calculates
cos(theta)+i*sin(theta)
To make cordicexp and exp same you need to use:
exp(i*theta)
Remember Euler's formula.
exp(i*x) = cos(x)+i*sin(x)

theta = -pi:pi/4:pi ;
y1 = exp(1i*theta) ;
y2 = cordiccexp(theta) ;
figure;
hold on
plot(1:length(y1),real(y1),'r','linewidth',2.5);
plot(1:length(y2),real(y2),'*b','linewidth',2.5);
grid on
legend('exponential','cordicexp');
