Thread Subject: Execution Time

hii,

Does anyone help me to find the execution time of my code(shown below), also m a newbie, any help to modify or make this code compliant to MAAB guideline is appreciated.

function vehiclespeed = Calspeed(WSFrR,WSFrL,WSRrR,WSRrL,FrRQF,FrLQF,RrRQF,RrLQF)
%#eml
% This block supports an embeddable subset of the MATLAB language.
% See the help menu for details.

if FrRQF ==3
     FrR_QF = True;
else FrR_QF = False;
end;

if FrLQF ==3
     FrL_QF = True;
else FrL_QF = False;
end;

if RrRQF==3
     RrR_QF = True;
else RrR_QF = False;
end;

if RrLQF ==3
     RrL_QF = True;
else RrL_QF = False;
end;

if (FrR_QF && FrL_QF && RrR_QF && RrL_QF)
      a = [WSFrR,WSFrL,WSRrR,WSRrL];
      vehiclespeed = Avg(a);
   
      elseif (FrR_QF && FrL_QF && RrR_QF)
              b = [WSFrR,WSFrL,WSRrR];
              vehiclespeed = Avg(b);
      elseif (FrR_QF && FrL_QF && RrL_QF)
              b = [WSFrR,WSFrL,WSRrL];
              vehiclespeed = Avg(b);
      elseif (FrR_QF && FrL_QF && RrL_QF)
              b = [WSFrR,WSFrL,WSRrL];
              vehiclespeed = Avg(b);
      elseif (FrR_QF && RrR_QF && RrL_QF)
              b = [WSFrR,WSRrR,WSRrL];
              vehiclespeed = Avg(b);
              
      elseif (FrR_QF && FrL_QF)
              c = [WSFrR,WSFrL];
              vehiclespeed = Avg(c);
      elseif (FrR_QF && RrR_QF)
              c = [WSFrR,WSRrR];
              vehiclespeed = Avg(c);
      elseif (FrR_QF && RrL_QF)
              c = [WSFrR,WSRrL];
              vehiclespeed = Avg(c);
      elseif (FrL_QF && RrR_QF)
              c = [WSFrL,WSRrR];
              vehiclespeed = Avg(c);
      elseif (FrL_QF && RrL_QF)
              c = [WSFrL,WSRrL];
              vehiclespeed = Avg(c);
      elseif (RrR_QF && RrL_QF)
              c = [WSRrR,WSRrL];
              vehiclespeed = Avg(c);
      
      elseif (FrR_QF)
              vehiclespeed = WSFrR;
      elseif (FrL_QF)
              vehiclespeed = WSFrL;
      elseif (RrR_QF)
              vehiclespeed = WSRrR;
      elseif (RrL_QF)
              vehiclespeed = WSRrL;
      
      else
              vehiclespeed = 0;
end;

function AvgSpeed = Avg(q)
SpeedAscend = Sort(q);
AvgSpeed = (SpeedAscend(1)+SpeedAscend(2))/2;

Hi there,

Since this is an Embedded MATLAB function block, you need to use the Simulink Profiler to get an undestanding of the execution time in context of the othe blocks in your model:

Thanks,

Sauabh

Many thanks, can u pls advise of any pitfall in my code or better ways of coding it?

Appreciate your help!!

well... did you even bother to look at what others have told you...

us

yeah I am not that lazy, it took 0.6% of total simulation time of entire simulink model. This function has been called 950 times, hence I wanna know if there is a better and faster implementation possible in embedded matlab. Any help...pls
