Hi,
The following is for a threshold value. The detects all values larger than a certain "threshold" value (in the code below it is 0.0193364). However, I need it to detect values between interval, for example, any value between 0 and 0.012.
Could anyone please help me? Thank you very much.
The code:
numfiles = 456;
threshold =0.0193364;
linesabovethreshold = zeros(numfiles, 1);
for fileidx = 1:numfiles
filecontent = dlmread(sprintf('result_%d.txt', fileidx));
assert(iscolumn(filecontent), 'file number %d has more than one column', fileidx);
linesabovethreshold(fileidx) = sum(filecontent >= threshold); %only works if file has only one column
end
dlmwrite('Fragility_mm.txt', linesabovethreshold / 1000);

Try this:
numfiles = 456;
low=0;up=0.012;
linesabovethreshold = zeros(numfiles, 1);
for fileidx = 1:numfiles
filecontent = dlmread(sprintf('result_%d.txt', fileidx));
assert(iscolumn(filecontent), 'file number %d has more than one column', fileidx);
linesabovethreshold(fileidx) = sum(filecontent >= low & filecontent <= up); %only works if file has only one column
end
dlmwrite('Fragility_mm.txt', linesabovethreshold / 1000);

It is included as you can see there is a equality sign as well in the condition.
filecontent <= up
