is it possibleto make gui of programme in which odesolver is used
i have made the programme for flatfire trajectory using ode solver (ode45), with event location .if i run it dirrectly from its solver it execute efficiently .
but when i try to execute this programme using a toggle button or push button it gives error
here is the function programme
function [value,isterminal,dircn] = fnflatfiredragwind(t,c,flag,w1,w2,w3,k)
g = 9.8;
% c(1) = x; c(2) = dx/dt = vx ; c(3) = y ; c(4) = dy/dt = vy ; c(5) = w
% c(6) = dc/dt = vz
if nargin<7 || isempty(flag)
value = [c(2); -k*(c(2)-w1)^2; c(4); (-k*(c(2)-w1)*(c(4)-w2))-g; c(6); -k*(c(2)-w1)*(c(6)-w3)];
else
switch flag case 'events'
value = c(3);
isterminal = 1;
dircn = 0;
otherwise
error('function not programmed for this event');
end
end
and here is the solver programme
v0 = str2num(get(handles.edit1,'string'));
theta = str2num(get(handles.edit2,'string')); theta = theta*pi/180; w1 = str2num(get(handles.edit3,'string'));
w2 = str2num(get(handles.edit4,'string'));
w3 = str2num(get(handles.edit5,'string'));
k = str2num(get(handles.edit6,'string'));
c0 = [0;v0*cos(theta);0;v0*sin(theta);0;0];
options = odeset('events','on');
tspan = [0 10];
[t,c,te,ze,ie] = ode45('fnflatfiredragwind',tspan,c0,options,w1,w2,w3,k);
please clarify my problem. i had asked problem regarding this before but answer is not satisfactory
