How to separate log file data containing different strings?

Hi,

I have my log file data in following format

15303,"Actual RPM","0.0"
15303,"Actual RPM","0.0"
15602,"RPM Error","1434.2168665609909"
15602,"RPM Error","1434.2168665609909"
15602,"Actual RPM","565.7831334390091"
15603,"Actual RPM","565.7831334390091"
15702,"RPM Error","1005.5968324944437"
15702,"RPM Error","1005.5968324944437"

and it continues in the similiar trend. I want to separate Actual RPM and RPM error so that i can plot them individually. How to do that?

fid=fopen('fic.txt')
line=fgetl(fid);
k=1;
while ischar(line)
  a{k,1}=line;
  line=fgetl(fid)
  k=k+1
end
fclose(fid)
rpm_error=regexp(a,'"RPM\s+Error","([\d\.]+)"','tokens','once')
rpm_error=cellfun(@(x) str2double(x),rpm_error,'un',0)
rpm_actual=regexp(a,'"Actual\s+RPM","([\d\.]+)"','tokens','once')
rpm_actual=cellfun(@(x) str2double(x),rpm_actual,'un',0)

Hi Azzi,

I am able to separate the data but when i am trying to plot it says not enough input arguments. I am attaching my log fie so that you can take a look.
