%WINDBARBM Project wind barbs onto map axes
%
% WINDBARBM(lat,lon,u,v) projects two dimensional wind barbs onto the
% current map axes. The vector components (u,v) are in units of knots and
% are specified at the points (lat,lon). It handles winds up to 130 knots.
% Winds exceeding 130 knots will appear as 130 knots.
%
% WINDBARBM(lat,lon,u,v,s) uses the input s to scale the vectors after
% they have been automatically scaled to fit within the grid. If omitted,
% s = 0.9 is assumed.
%
% WINDBARBM(lat,lon,u,v,'PropertyName',PropertyValue,...) and
% WINDBARBM(lat,lon,u,v,s,'PropertyName',PropertyValue,...) uses the
% windbarbm object properties specified to display the windbarb objects.
% The properties supported by windbarbm are the same as the properties
% supported by linem.

I have U and V..but vertically, how can I use windbarbm

I tried windbarb(ht,1,U,Y)

got error :

Error using windbarbm (line 41)
Inconsistent dimensions for inputs.

can anyone help

htt is matrix with height.
1 is any arbitrary point

For me I got the same error as Nicholas on line 161. To fix the undefined function "linem" error, replace

eval(['linem(y,x,',wbproperties,')']);

with

eval(['line(y,x,',wbproperties,')']);

and it works perfectly!

I keep getting this error even though my array is double and 2d:

Error using LINEM
Expected input number 1, LAT, to be one of these types:

double

Instead its type was single.

Error in linem (line 57)
validateattributes(lat, {'double'}, {'2d'}, 'LINEM', 'LAT', 1)

Error in windbarbm (line 161)
    eval(['linem(y,x,',wbproperties,')']);

Updates

1.3

Now accommodates user specification of wind barb properties (e.g., 'Color', 'LineWidth', etc.)

1.2

Now handles winds up to 130 knots.
