How to identify occurences in a text file and save both number and text into arrays

2 views (last 30 days)
Hi,
I would like to open an external text file, with n lines and identify the lines which start with "VAR="
A typical line has "VARx=S", where x and S are integers. So, an example is VAR1=2
How can I save, for example:
Textarray=[VAR1,VAR2,VAR3,VAR4]
integerarrray=[2,4,6,7]
The code must be able to identify all the occurences where the line of the external text file starts with "VAR". The text above is just an example.
Right now, the code that I have only (attempts) to count the number of variables in my text file.
nvar=0
for i=1:1:nlines
fid = fopen('C:\code\a.txt','w');
k=strncmp(fid,'VAR',3)
if k==1
nvar=nvar+1
end
end
Any help is appreciated.
Thank you,
