Hello,
I'm looking for solution to compare two vectors:
traj_cnt = 0;
t_row_cnt = 0;
m_row_cnt = 0;
global_TP = 0;
global_FN = 0;
global_FP = 0;
global_TN = 0;
error_cnt = 0;
motorspeed_detected(length(Traj_interpl)) = 0;
motor_actual(length(M_interpl)-1) = 0;
var = 2;
harm = 10;
TP_help = 0;
FN_help = 0;
FP_help = 0;
TN_help = 0;
TN_debug = 0;
TP=0;
FN=0;
FP=0;
TN=0;
motor_detection_cnt = 0;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Actual time slot calculation
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
for t_ref_cnt = 385%1:length(t_ref) %for every 10ms time step
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
for m_interpl_cnt = 2:length(M_interpl) %for any motor
for m_row_cnt = 1:length(M_interpl{m_interpl_cnt}) %for any row of single motor
if t_ref(t_ref_cnt) == M_interpl{1}(m_row_cnt) %if right row of motor is choosen
motor_actual(m_interpl_cnt-1) = M_interpl{m_interpl_cnt}(m_row_cnt); %write aktual value of motorspeed to array
break;
else
motor_actual(m_interpl_cnt-1) = 0;
end
end
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
for traj_cnt = 1:length(Traj_interpl) %for every Traj-Cell
for t_row_cnt = 1:length(Traj_interpl{traj_cnt}) %for any row of Traj
if t_ref(t_ref_cnt) == Traj_interpl{traj_cnt}(t_row_cnt,1) %if right row of Traj is choosen
motorspeed_detected(traj_cnt) = Traj_interpl{traj_cnt}(t_row_cnt,2); %write detected value to array
break;
else
motorspeed_detected(traj_cnt) = 0;
end
end
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Beginn TP/FP
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
if (any(motor_actual))
for m_act = 1:length(motor_actual) %for any motor
for s_act = 1:length(motorspeed_detected) %for any detected speed
for harm = 1:10
for tube = var %for variable tube
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% True positive % TP % motor is running, motorspeed detected !!!!!!!!!!HERE IS A PROBLEM
if (any(motorspeed_detected))
if (motorspeed_detected(s_act) >= (motor_actual(m_act) * harm) - tube) && (motorspeed_detected(s_act) <= (motor_actual(m_act) * harm ) + tube) %Right speed detected
global_TP = global_TP + 1; %DEBUG
TP_help = TP_help + 1;
elseif (motorspeed_detected(s_act) > ((motor_actual(m_act) * harm) + tube) && (motorspeed_detected(s_act) < ((motor_actual(m_act) * (harm + 1)))- tube)) %Wrong speed detected -> FN
global_FN = global_FN + 1; %DEBUG
FN_help = FN_help + 1;
else
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% False negative % FN % motor is running, motorspeed not/ wrong detected
elseif (~any(motorspeed_detected))
global_FN = global_FN + 1;
FN_help = FN_help + 1;
else
end
end
end
end
end
elseif (~any(motor_actual))
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% False positive % FP % motor is not running, unknown motorspeed detected
if (any(motorspeed_detected))
global_FP = global_FP + 1;
FP_help = FP_help + 1;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% True negative % TN % motor is not running, no motorspeed detected
elseif (~any(motorspeed_detected))
global_TN = global_TN + 1;
TN_help = TN_help + 1;
TN_debug(TN_help)= t_ref_cnt;
else
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
else
end %end of TP/FP
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
if (TP_help >= 1) || (TP_help >= 1 && FN_help >= 1)
TP = TP + 1;
elseif FN_help >= 1 && TP_help == 0
FN = FN + 1;
elseif (FP_help >= 1)
FP = FP + 1;
elseif (TN_help >= 1)
TN = TN + 1;
else
error_cnt = error_cnt + 1;
end
TP_help = 0;
FN_help = 0;
FP_help = 0;
TN_help = 0;
end
Vectors look for actual time slot:
motor_actual =
37.3321 0 0 0
motorspeed_detected =
Columns 1 through 21
0 40.7246 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Columns 22 through 24
0 0 0
So, idea to detect values of all motor_actual values +-tube (tube is just a static value first) and increase TP_help if motorspeed_detected value (37.33+-2)*harm if not to increase FN_help value. (by multiple detection at least one right value - all motorspeed_detected vector passed -> TP_help increase)
I think, I make mistake by using:
if(motorspeed_detected(s_act) >= (motor_actual(m_act) * harm) - tube) && (motorspeed_detected(s_act) <= (motor_actual(m_act) * harm ) + tube)
because it is a logical expression:
(motorspeed_detected(s_act) >= (motor_actual(m_act) * harm) - tube) is while motorspeed_detected(s_act) = 0 and motor_actual(m_act) * harm) = 0
Like a 0 >= 0 - 2 and the second part the same. And -2 && -2 is logical TRUE. So, for all zeros compare is my if-block TRUE. It's not an aim. How can I solve it? Maybe there are also some elegant solution to avoid multiple for-cycles?
Thank you very much in advance!

I solve it by elimanating a zeros:
% True positive % TP % motor is running, motorspeed detected
if (any(motorspeed_detected)) && (motorspeed_detected(s_act)) && (motor_actual(m_act))
for harm = 1:10
if (motorspeed_detected(s_act) > (motor_actual(m_act) * harm) - var) && (motorspeed_detected(s_act) < (motor_actual(m_act) * harm ) + var)
global_TP = global_TP + 1;
TP_help = TP_help + 1;
else
global_FN = global_FN + 1;
FN_help = FN_help + 1;
end
end

Maybe you have some arguments abour whole code!?
