显示 更早的评论
and how Evaluate the function at input values of x & n determined by the user, then keep the real part of the complex result at A and the imaginary part at B.

What have you tried?

I am learning new and do not understand it wellf = @(x,n) x.^(1i.^(n-1)+2./n) - 1i*abs(5*cos(exp(1i.*sqrt(n).*x)))
real(f(4,3))
imag(f(4,3))

Note: syms requires the Symbolic Toolbox be installed and licensed.
@Walter Roberson is right.
if you run it with Symbolic Math Toolbox, it goes as follows:
syms x n i
f = x^(i^(n-1)+2/n) - abs(5*cos(exp(1i*sqrt(n)*x)))

I think i = sqrt(-1) there, and also a trailing i got missed
syms x n
f = x^(i^(n-1)+2/n) - abs(5*cos(exp(1i*sqrt(n)*x)))*i

Since you don't seem to have a licence for the symbolic toolbox, I showed you a way how to circumvent symbolic computations.
And since you don't want to "solve" or "dsolve" anything, I also don't see the necessity to go the symbolic way.
