Estoy haciendo una tarjeta de adquision de datos en matlab, que me envia y recibe datos de forma serial, al precionar un boton que inicie y otros 2 que al precionarlos, me envian un caracter por el ´puerto serial, pero me maqrco un error y no se el porque. a continuacion envio el codigo.
ERROR
>> ADQ
In an assignment A(:) = B, the number of elements in A and B must be the same.
Error in ADQ>pushbutton1_Callback (line 119)
q(1) = fscanf(s,'%d %d %d %d');
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in ADQ (line 43)
gui_mainfcn(gui_State, varargin{:});
Error in
