Undefined function for input arguments of type ‘matlab.ui.Figure’.
Hi All,
Trying to run the following code by calling imspline (imspline is a defined class: classdef imspline < handle):
h = imspline(gca,’lineColor’,[1 0.5 0],’pointColor’,[0.2 0.8 0.4],’lineWidth’,5);
It gives this error: Undefined function ‘addImPoint’ for input arguments of type ‘matlab.ui.Figure’. Please give some suggestions. Would this error related to MATLAB versions? Thanks a lot in advance.
