how to implement an FIR bandpass filter element vice

i wanna implement an fir bandpass filter in matlab, which filters a given signal element vise. code should contain a loop which feeds the samples one‐by‐one into the filter as if the signal is acquired in real time. any help will be appreciated . the function should look like. value myFIR(value, coefficients)

It is not possible to do what you want. The signal vector has to be at least 2 times the length of the longest filter coefficient vector in a discrete filter.

Use an active hardware filter instead, in the input to your ADC.
