So I have a text file and i need to store the sampling rate value like this:
samplingRate1 = 1000;
samplingRate2 = 2000;
I don't know how to find and store these values. The next thing is that the text file is very long but I only have to read the second line.
I tried using textscan but I am doing something wrong i think.
Any suggestions.
text file:
#kjkjj,lzddz;mzdm;dzm;mdz
# { {"sensor": ["CUSTOMV"], "device name": "00:07:80", "sampling rate": 1000, "position": 1, "sampling rate":2000, }}

Hi,
To read the sampling rates mentioned in the text file 'regexp' is your best bet.
You can do so by:
s = fileread('test.txt'); % your text file's name
W = regexp(s,'"sampling rate":\s*([0-9]*)','tokens');
result = [W{:}].'
Also, to read a particular line number from a text file, you can refer to the solution provided here.
Hope this helps!
