yogeshwari patel’s ‘Answer’ became this Comment —
x = linspace(0, 400, size(u,2));
t = linspace(0, 6, size(u,1));
size(u,2) ?
can u explain this twwo line what i understands is it will generate the grid 400/size(u,2).

Sure.
It does not need to generate a grid (matrix), because the first 2 arguments to surf (or mesh) can either be matrices or vectors. The dimensions simply need to match the third argument (that must be a matrix). So defining them as vectors is good enough, and that is what my correction to the earlier code does.
The easiest way to do this is to use the linspace function, since it allows the most direct control of the vector length.
