Store value from text file

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, }}

3745 0 6595 6752 8053 5587 6 0 11271 6408 7641 1944

........(keeps going)

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!
