How do I pass the signal through a low-pass FIR filter?

I have a string called the signal. I want to pass it through a low pass FIR filter very close to this signed ideal. How can I do it?
signal=1x732
signal=[-0.0029, 0.0117, 0.0068, ...,0.4467, 0.5054]

if ‘h’ are the numerator vector of the filter (and the filter is designed correctly) —
signal_filtered = filtfilt(h, 1, signal);
That should work.

In this example, ‘h’ is a vector of coefficients returned by the funciton that designs the FIR filter (or that you calculate). How you design the filter is your choice, depeding on your reqquirements.
