trying to plot zonal and meridional wind data via the "quiver" command and I get the following error:
Error when using quiver (line 58) The size of X must match the size of U or the number of columns of U.
The data I used is attached (.mat) on google drive, it has 90mb, so I didn't put it here. follow the link: https://drive.google.com/open?id=18GgPs-iN3brZHQ3pZNK8GyLt4SOmemY8&authuser=costapereira620%40gmail.com&usp=drive_fs
Anyone a solution??
% load 'dat_era5_201007.mat'
%%
t1 = datetime(2007,07,1,0,0,0); % 01/jul/2007 as 00h
t2 = datetime(2007,07,31,23,0,0); % 31/jul/2007 as 23h
t = t1:hours(1):t2; % sera gerado datas no intervalo de t1 a t2
%%
cd 'H:\DADOS_SCi-MSc\DadosEra5PreComp'
data1 = load('dat_era5_201007.mat', 'u10');
data3 = load('dat_era5_201007.mat', 'v10');
u10=data1.u10;
v10=data3.v10;
u10=u10(:,:,t==t);
v10=v10(:,:,t==t);
u10mean=mean(u10,3);
v10mean=mean(v10,3);
load('dat_era5_201007.mat', 'lon');
load('dat_era5_201007.mat', 'lat');
%%
figure
[x, y]=meshgrid(lon(:,1),lat(:,1));
quiver(x,y,u10mean,v10mean)

You have created x and y so that they are 53x57 arrays, but u10mean and v10mean are 57x53. As the error message says, they must be the match.
Try this instead.
[x, y]=meshgrid(lat(:,1),lon(:,1));
quiver(x,y,u10mean,v10mean)
