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

theta = -pi:pi/4:pi ;
y1 = exp(1i*theta) ;
y2 = cordiccexp(theta) ;
hold on
grid on

I need below and not imaginary of cordic exponential.
theta = [-pi:pi/4:pi];
y = cos(theta)+i*sin(theta);
y1 = cordiccexp(theta); % imaginary
y2 = exp(theta); % no imaginary
subplot(2,1,1);plot(1:length(y),real(y1),'r--','linewidth',2.5); hold on; grid on;legend('cordicexp');
subplot(2,1,2);plot(1:length(y),real(y2),'b--','linewidth',2.5); hold on; grid on;legend('exponential');
