Please find the attached file that included "LEV(57*1), LON(100*1) and LAT(44*1)" parameters. I want to convert "LEV" to LEV(57*44*100). Thanks for your kind help.

You currently have 57 elements in LEV. In total with your 3 matrices, you have 57+100+44 == 201 elements. You tell use you want a new matrix with 57*44*100 == 250800 elements. Where do the extra elements come from? Why do you want a 3D matrix?

I would to plot a profile corresponding to a specific longitude and latitude. Thanks

You don't have this information at the moment. You would indeed need a 57*44*100 matrix to do this, but it needs to be something you already have, you can't make it up.
I suspect that the LEV you have is the profile at ONE of these latitude/longitude coordinates.

clc
clear all;
close all;
z=zeros(44,57);
z(:,1)=LAT;
z(1,:)=LEV;
z(1,1,1:100)=LON;
volshow(z)

problem is the surface value, if you see the corresponding value for the depth at the seasurface is not zero
25.1250000000000 ---------------> it shoud be "0"

It makes no sense to construct a volume taking some values from the latitude and longitude and some from the measurement at these coordinates. LAT and LON are the coordinates of the points in the volume, they're not the volume data.

Dear Guillaume, You are right, I did other way. Thanks
