Two for loops running simultaneously

Hi fellow experts,

I'm trying to design a matlab GUI where the user can key in the desired value in the display box which will display the output of the Arduino in graph. eg. if i key in 3 on the display box, the graph will show the output of the Arduino in 180 seconds. I am currently stuck at this stage as the For loops at b=2 would keep overlapping with b=1.

a=arduino
b = get(handles.edit1, 'String')
for b=1;
      for d=1:60
      temp(d)= readVoltage(a,'A15');
      plot(temp);hold on;
      pause(0.2);
      end
end
for b=2;
   for i=1:120
      temp(i)= readVoltage(a,'A15');
      plot(temp);hold on;
      pause(0.2);
   end
end

etc.

Any form of help would be greatly appreciated!!

Thanks

Jacob

[dpb]

b = get(handles.edit1, 'String')
N=int(str2num(b)*60);
temp=zeros(N,1);
for d=1:N
  temp(d)= readVoltage(a,'A15');
  plot(temp);hold on;
  pause(0.2);
end

Hi

i tried with your solution and it came out as

Undefined operator '*' for input arguments of type 'cell'.

b is a cell array because it's more than 1 line. So after you get b, try

b = b{1};

or

b = char(b);

If you really want for loops to run simultaneously, you'd need the Parallel Processing Toolbox and use the parfor command instead of the for command.
