How to modify the command "find" to make it find values in interval?

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);

Thanks Birdman. I think it worked. I just would like to ask if the 0.012 is included in the selection of the values or it is out of the range?

[Birdman]

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

filecontent <= up

Great. Thank you very much Birdman. Your insightful responses were awesome as usual.
