MATLAB: Histogram struggles (excluding low values and multiplying all the data)

Question

Hi,

I’m trying to make histogram out of some data

lc = cellfun(@(c) c(end,6),particles);
hist(lc, 20)

How do I exclude values lower than 2 from the histogram? (as this back ground noise and looks messy)

ALSO – the data is current in the wrong units and I would convert it by multiplying by 7.431 (for example)

So to apply this to the data in the histogram would I do:

lc = cellfun(@(c) c(end,6),particles)
f=lc*7.431
hist(f,20)

Thanks in advance 🙂

Answer 1

Use masking:

goodIndexes = particles >= 2;
histogram(particles(goodIndexes), 20);

particles is your data array.
