MATLAB: GeodataLogger via Matlab with plot_google_map

arduinodata importdatalogdataloggergeodatageodataloggoogle_mapsgpsgps_datamapsmatlab_gpsmatrix manipulationplotting

I am working on a project which requires geodata logging via Matlab, I want it to plot big red dots when acceleration on z-axis goes above 410, and plot normal size blue dots when acc_z value is below 410. I am using plot_google_map function for plotting google maps image.
Here is my code:
lat = [48.8708 51.5188 41.9260 40.4312 52.523 38.274179];
lon = [2.4131 -0.1300 12.4951 -3.6788 13.415 27.074541]; 
acc = [333 327 405 ; 334 327 440 ; 327 323 412 ; 325 321 425; 325 320 430; 400 400 400];
acc_z=acc(:,end);
i=1:length(lat);
k=1:length(lon);
j=1:length(acc_z);
raw_data=[lat ;lon ;acc_z'];
raw_data_acc=raw_data(3,:);
for m=1:length(j)
     if (raw_data_acc(j))>410   
         plot(lon,lat,'.r','MarkerSize',40) 
         hold on 
     else
         plot(lon,lat,'.b','MarkerSize',20)
     end
  end
  plot_google_map
and here is my plot:
as you can see 2nd,3rd,4th and 5th dots must be big,red. But unfortunately i am not able to plot them as i want.
Any kind of help is appreciated.

I think your whole script can be replaced by this:
lat = [48.8708 51.5188 41.9260 40.4312 52.523 38.274179];
lon = [2.4131 -0.1300 12.4951 -3.6788 13.415 27.074541]; 
acc = [333 327 405 ; 334 327 440 ; 327 323 412 ; 325 321 425; 325 320 430; 400 400 400]; 
                                                       %   
% Get indices 3rd column of acc values greater than 410: 
bigthan410 = acc(:,3)>410;
                                                       %


% Plot the big ones as big red dots: 
plot(lon(bigthan410),lat(bigthan410),'.r','MarkerSize',40) 
hold on
                                                       %
% Plot the non-big ones as smaller blue dots: 
plot(lon(~bigthan410),lat(~bigthan410),'.b','MarkerSize',20)
                                                       %
plot_google_map
