Default MATLAB Streamslice error

Greetings all -

I am trying to plot streamlines for my 2-D FVM Matlab code but my scale is not what I'd like it to be (this is more of a MATLAB plotting question rather than a CFD theory question)

My code snippet for the streamslice is as follows.

%%%%%%%%%%%%%%%%%%%%%%%%%%
% Generate Streamline plot
uvect=zeros(nodes_x,nodes_y);
vvect=zeros(nodes_x,nodes_y);
for i=1:nodes_x-1;
for j=1:nodes_y-1;
uvect(i,j)=0.5*(u(i,j)+u(i+1,j));
vvect(i,j)=0.5*(v(i,j)+v(i,j+1));
end
end

figure(5)
[X,Y]=meshgrid(0:x,0:y);
streamslice(X,Y,uvect,vvect);

%%%%%%%%%%%%%%%%%%%%%%%%%%

My plot window goes from 0 to 10 (x and y values) but I want it to go the width and length of my boundary (denoted as width and length). However when change the meshgrid (0:x,0:y) I keep getting an error

Anyone got any ideas? I'm pretty sure I'm just missing but I'm not seeing it. Thanks for reading!
