Dear all,

i would like to convert a matlab file into a shape file. I wrote the code below, however an error message is still appearing (sea below), does someone have any ideas how to solve it, pelase?

Error message:

error using shapewrite

Expected input number 1, S, to be a vector.

Error in shapewrite>parseInputs (line 667)

validateattributes(S, ...

Error in shapewrite (line 82)

[S, basename, dbfspec] = parseInputs(varargin{:});

Error in average_current (line 137)

shapewrite(Data, 'EBB_current.shp');

 %% Convert to shape file
clear all
close all
clc
% assign the path to your working directory:
cd ('E:\publi\Waiting-room\bird_swnasea\Velocity_file\');
file = 'Average_EBB.mat';
load(file,'U','V');
Data = struct([]) ;  % initilaize structure
for i = 1:141 % number lines of matrices U and V
    for j = 1:161 %number of column of matrices U and V
Data(i,j).Geometry = 'Polygon' ;
Data(i,j).X = U(i,j)  ;  % latitude
Data(i,j).Y = V(i,j);  % longitude
Data(i,j).Name = 'EBB' ;   % some random attribute/ name
    end
end
shapewrite(Data, 'EBB_current.shp');
