Do I understand correctly that you want a plot with four independent directions?

And then F would be the dependent direction, for a total of 5 dimensions in the plot ?

I am not clear as to whether you want exp(1i*y) or exp(y)*1i ?

This will not be a vector. You have absolute minimum of two independent directions, x and y, so your result cannot be less than a surface.

x = linspace(-1,1) ;

y = linspace(-1,1) ;

[X,Y] = meshgrid(x,y) ;

% F = e^y i + x*e^y j

u = exp(Y) ;

v = X.*exp(Y) ;

quiver(X,Y,u,v)
