how to correct Too many input arguments error in below code

Too many input arguments. Error in 'sm_pick_and_place_robot/Planning and Control/Forward Kinematics' (line 15) [eePos, eeVel, guessValsOut, status] = sm_pick_and_place_robot_fk(actuatorPos, actuatorVel, guessValsIn);

Above lines are occurs errors

this is the code

function [eePos, eeVel, guessValsOut] = FK(actuatorPos, actuatorVel, guessValsIn)

% Wrapper around sm_pick_and_place_fk.m, which creates a persistent

% KinematicsSolver object for the forwards kinematics problem and then

% solves it.

coder.extrinsic('sm_pick_and_place_robot_fk');

persistent init

if isempty(init)

init = true;

eePos = zeros(3,1);

eeVel = zeros(3,1);

guessValsOut = zeros(3,1);

status = 1;

end

[eePos, eeVel, guessValsOut, status] = sm_pick_and_place_robot_fk(actuatorPos, actuatorVel, guessValsIn);

if status ~= 1

error('fk solve failed')

end

please help me guys

sm_pick_and_place_robot_fk is not a function that I can find anywhere. We have no information about how it is defined, but apparently it does not expect three inputs

[chrisw23]

check this

[eePos, eeVel, guessValsOut, status] ...

[Ruchira]

still same error occured,now

erros,

'Output Port 4' of 'sm_pick_and_place_robot/Planning and Control/Forward Kinematics' is not connected.
