Dear all,
I have a velocity field in a lake whichis contructed on a (m,n,k) grid where m is the number of grid points in the x-direction, n in the y-direction and k the number of vertical layers. At the moment, I have 100 layers (so k = 100) distributed over a depth of 350 meters. I would like to interpolate this velocity field to 200 layers in the vertical distributed over the same depth. I thought the following piece of code would work, where z1 is a (1,100) array containing depth layers and z2 a (1,200) array containing 200 depth layers on which I would like the velocity field to be interpolated. This code does not work since I get the error that X and V must be of the same length. But they are of the same length, right? Does anyone know how to code this properly?
Many thanks in advance!
for i = 1:m
for j = 1:n
interp_u = interp1(z1, u(i, j, :), z2, 'linear')
