I have (N = 550) grid points starts from a = 0, to the end point b = 291.5. the spatial grid step is dx = 0.53. I want increase the grids between a and b by decreasing dx, without changing N.
Here the codes i used
N = 550; % number of grid points
x = linspace(a, b, N+1)'; % cell interfaces
dx = x(2) - x(1); % spatial grid step
xc = 0.5*(x(1:end-1) + x(2:end)); % centers of cells

By definition
dx = (b-a) / N
So again, you can't change dx without changing at least one variable on the other side of the equation.
