How can I mesh plot the array of a shape 1x51x51 (double)

I am trying to analyse the mode profile inside the waveguide. And the software gives me the following plot.

The plot shows the mode profile in a bended waveguide.

When I try to export this data to matlab I get the data shaped 1x51x51 (E_intensity ). How can I manipulate this to get the same plot as shown in the image. Attached is the data.

Try the folloiwng, noticed that the axis X and Y may be inverted and you need to verify and confirm the correct direcitons.

load('E_field.mat');
newE2 = squeeze(E_intenisty);
figure
[Ny,Nx]=size(newE2);
[X,Y]=meshgrid(1:Nx,1:Ny);
ax = gca;
pcolor(ax,Y,X,newE2)
hold on
shading interp
colorbar
colormap(ax,jet);

Thanks a lot this is exactly what I want!

E_new = squeez(E2);
surf(E2);
