A matrix/grid from two vectors

Dear all,
I am trying to construct a matrix (or a grid) with specific limits on the x and y axes from two vectors:
ns = 20; %number of points on S axis
np = 20; %number of points on P axis
S = linspace(0,1,ns); %S variable
P = linspace(-1,1,np); %P variable
The resulting grid I want has the follwoing shape (just for an illustrative purpose. Surely the number of points would be larger):
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/547338/image.jpeg)
I have thought about "meshgrid(S,P)" command, but it won't help as it doesn't let me have the specific P limits that I want, as shown in the photo above.
Any help would be appreicated!
Thanks,
Lama

ns = 20; %number of points on S axis
np = 20; %number of points on P axis
s = linspace(0,1,ns); %S variable
p = linspace(-1,1,np); %P variable
[S,P] = meshgrid(s,p);
% mesh needs X,Y and Z so create z
Z = zeros(size(S));
mesh(S,P,Z,'Marker','o','MarkerFaceColor','k','EdgeColor',"k")
axis equal tight
