I am trying to create a DLL from a function in which I am using the "getCursorInfo" command. However, when compiling the DLL it gives the following error: Undefined function or variable 'getCursorInfo'.
Could someone help me please?
My function code is as follows:
function [pts] = getpts2d(x,y,n)
%% getpts2d Select points from a 2D plot by clicking on plot
% x - Vector of X coordinates
% y - Vector of Y coordinates
% z - Vector of Z coordinates
% n - Number of points needed to be selected
% pts - Returns a n x 3 matrix of selected points
h = figure;
plot(x,y);
pts = zeros(n,2);
datacursormode on
dcm_obj = datacursormode(h);
hold on
for i=1:n
%display(sprintf('Click on figure for point %d',i))
%waitforbuttonpress;
pause;
key=get(gcf,'CurrentKey');
if strcmp(key,'space'),
% Press space to continue peak selection
f = getCursorInfo(dcm_obj);
ptosi = f.Position;
plot(ptosi(1),ptosi(2),'o','MarkerEdgeColor','g','MarkerFaceColor','g')
pts(i,:) = f.Position; % Mark this peak as green
else
% Press any other key to ignore this peak
plot(ptosi(1),ptosi(2),'o','MarkerEdgeColor','r','MarkerFaceColor','r') % Mark this peak as red
end
end
end
obs. To create the DLL I'm using the command "codegen"
