how to plot a vector?

The vector questionis F=e^y i + x*e^y j

how do I plot this equation on matlab

[Walter Roberson]

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

1. x
2. y
3. complex direction #1, "i"
4. complex direction #2, "j"

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)
