if this is used for calculating low-pass
lp=(wc/pi)*sinc((wc/pi)*M);
how can I calculate the highpass?

Use the Signal Processing Toolbox lp2hp function.
For an IIR filter, you have to have numerator and denominator polynomials, so what you posted may not define an IIR filter. I am not certain what you are doing.
