Digital low pass filter without signal processing toolbox

Hi all,
All I need to do is create a low pass filter for a 1D array.
This should be very very simple but it seems all the literature requires the signal processing toolbox.
Sampling rate is 2kHz, want to filter everything above 60Hz.
Any help? TIA

You can always go back to the literature and implement the equation yourself.
Say if you want to design an FIR low pass filter using window method, then the following link gives you the step by step instruction on how to calculate the filter coefficients
