x_array: Array of coordinates of x-position in the channel
y_array: Array of coordinates of height positions at the channel entry
velocity_array: Array of velocities at the height positions at the channel entry
(Arrays y_array and velocity_array have the same size).

Then you could proceed as follows:

n=length(x_array)
m=length(y_array)

x_quiver_array=zeros(m*n);
y_quiver_array=zeros(m*n);
x_velocity_quiver_array=zeros(m*n);
y_velocity_quiver_array=zeros(m*n);

For i=1:n
For j=1:m
x_quiver_array((i-1)*m+j)=x_array(i);
y_quiver_array((i-1)*m+j)=y_array(j);
x_velocity_quiver_array((i-1)*m+j)=velocity_array(j);
y_velocity_quiver_array((i-1)*m+j)=0.0;
end
end

quiver(x_quiver_array,y_quiver_array,x_velocity_quiver_array,y_velocity_quiver_array);

Best wishes
Torsten.
