Error using Timerfcn: too many input arguments

Question

1 个投票

Hello. I created this timer

t = timer('Period', delay, 'TimerFcn', calculate(V, g, n, Vmin, Vmax));

which calls a function named "calculate"

function  calculate
...
end

What's wrong with this code? Matlab returns this error message: ??? Error using ==> simulation>calculate Too many input arguments.

The Timerfcn is automatically passed two inputs, a handle to the timer and some event data.

In order to do what you have above (where you don't need either of the two given inputs) would be to use an anonymous function to absorb them:

t = timer('Period', delay, 'TimerFcn', @(~,~)calculate(V, g, n, Vmin, Vmax));

The '~' just ignores the input.

Also, your function calculate looks like it doesn't take any inputs. It would need to accept at least 5:

function  calculate(V, g, n, Vmin, Vmax)
...
end
