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!!

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?
