I have a .txt file which is an output of a simulation software.I want to scan the txt file for a variable & collect that variable's value at each occurence & take its mean.
The text file is of the format:
*****************************************************************:
ID : 1010
A0 : 2.650000e+001
A1 : 2.650000e+001
time : 7.391000e+003 ns
mod : 0
sat : 0
angle : 0.000000e+000 radians
freq : 7.493000e+002 MHz
count : 0
*****************************************************************:
*****************************************************************:

A0 : 2.850000e+001
A1 : 2.850000e+001

mod : 0
sat : 0
angle : 0.000000e+000 radians
freq : 7.493000e+002 MHz
count : 1

So for the above text file if i have to search for say freq i should get [7.493e+2 7.493e+2 7.493e+2] whose mean is 7.493e+2 MHz.
My code as of now:
fid = fopen('ch0_TC_SYS_01.txt','r');
text = textscan(fid,'%s','Delimiter','');
text = text{1};
fid = fclose(fid);
idx = find(~cellfun('isempty',strfind(text,'freq : ')));
text(idx)
With the above code i get something like this:
'freq : 7.493000e+002 MHz'
'freq : 7.493000e+002 MHz'
'freq : 7.493000e+002 MHz'
...
and after this i'm doing :
cellfun(@(x) x(8:20),abovecellarray,'un',0);
str2double;
But how can i do this dynamically seperating the units & all ?
