How can I to plot wind vectors from a netcdf file?

Hi everyone!

I am trying to plot wind vectors from netcdf file with quiver.m function, but then

??? Error using ==> quiver at 77 Matrices X and Y must be the same size as Z.

when I enter

 quiver(x,y,mat1,mat2);

in

varname1='uwnd';
[lat,lon,time,mat1,var1,unit1]=read_WWNC_var(filename,varname1);
varname2='vwnd';
[lat2,lon2,time2,mat2,var2,unit2]=read_WWNC_var(filename,varname2);
[x,y] = meshgrid(lon,lat);

how cai I to plot it?,

please help!!

What is size of x,y,mat1 and mat2? To use quiver all the dimensions shall be same.

Yes, I am sure, both are of same size.

[LUCK RH]

You are right!! Sizes are diferent: lat= [241 1] lon= [380 1] mat1= [380 241 97] mat2= [380 241 97]

Have you got some sugestion for me?

2 Dimensional arrays read from netCDF files often come out transposed compared to what you would expect. Try

quiver(x, y, mat1.', mat2.')

Thank you Walter, but now I have a new error message:

if true
 "Error using ==> transpose
  Transpose on ND array is not defined."
end

How can I to solve it?

LUCK RH did you ever get an answer to your above problem? I have the same issue.
