GUI Interpolation calculator, Indices exceeds array?

5 views (last 30 days)
I have been working on a GUI interpolation calulator I am required to code. I have gotten the majority of it completed, then I changed one thing and the code broke. I can not figure out why on line 136, handle.P_r "Index exceeds the number of array elements (1)." when its 1x25. I am only working with the edit_h_call back which I have marked with %*
function varargout = Interp_calc(varargin)
% INTERP_CALC MATLAB code for Interp_calc.fig
% INTERP_CALC, by itself, creates a new INTERP_CALC or raises the existing
% singleton*.
%
% H = INTERP_CALC returns the handle to a new INTERP_CALC or the handle to
% the existing singleton*.
%
% INTERP_CALC('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in INTERP_CALC.M with the given input arguments.
%
% INTERP_CALC('Property','Value',...) creates a new INTERP_CALC or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Interp_calc_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Interp_calc_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

I am now running into an issue where my radiobutton dose nothing, I'm guessing that once it pushed the GUI is not updateing. I have updated the posted code to include guidata(hobject,handles) to the radiobutton callback though this has not fixed the issue.

clear i j n
guidata(hObject,handles)
clear the loop counter variables used inside the callback function every time the GUI object is accessed. Try this approach

This plus getting rid of the repetative n+1 seems to have worked.
