hi guys i am trying to make a switch case . however, the code i have involves a function calling other functions and so i cant create the switch. (when i create the switch and remove the function title for the subfunction, the main function cant run the case. for example:
function main
for ...
Y = EulerODE(tspan, Init,dt, Repressor, Vm(i), Kx(i));
...
...
...
...
end
...
...
Y = EulerODE2(tspan, Init,dt);
...
end
%subfunction 1
function Y = EulerODE(tspan,init,dt,Repressor,Vm,Kx)
...
end
%subfunction 2
function Y = EulerODE2(tspan,init,dt)
end

Is there an error message? If so show us the full error message.
I assume that your problem isn't caused by the switch-statement. What happens if you comment out the switch-statement?
"and memove the function title for the subfunction" what exactly does that mean?

i havent actually made a switch because what ive tried isnt working. what ive written above works fine. basically i want to change what ive written in my question to something like what ive written below but i believe i cant have a function inside the switch? :
function main
switch
case1
for ...
Y = EulerODE(tspan, Init,dt, Repressor, Vm(i), Kx(i));
...
...
...
...
end
function Y = EulerODE(tspan,init,dt,Repressor,Vm,Kx)
...
end
case 2
...
...
Y = EulerODE2(tspan, Init,dt);
...
function Y = EulerODE2(tspan,init,dt)
end
end %end switch
end %ends function main

Hey Geoffrey,
Which version of MATLAB are you using? If you remove the main "function" declaration, it will consider the file to be a script. Local functions in scripts only started being supported in R2016b, so if you have a version earlier than that, then MATLAB will error. If you would prefer to use a script, you'll need to make separate function files for each of your local functions.

im using the online version of matlab, i have also the R2019b version. i havent actually made a switch because what ive tried isnt working. basically i want to change what ive written in my question to something like what ive written below but believe i cant have a function inside the switch? :
function main

case 2

...
Y = EulerODE2(tspan, Init,dt);
...
function Y = EulerODE2(tspan,init,dt)
end
end %end switch
end %ends function main

You are correct that functions cannot be defined inside control statements such as switch or if.
You can move all of the nested function definitions to just inside the "end" statement of the function.
