Designing a first-order IIR filter |

I can use the `freqz' function to find the cutoff (-20 dB) frequency
for a given filter, specified by its IIR coefficients and sampling
period. However, if I have a desired cutoff frequency and given
sampling period, how do I find the IIR coefficients that give the
desired first-order filter?
Many thanks in advance,
Shaun
