The MATLAB codes are based on our recent paper:
M. Nagahara and Y. Yamamoto,
Frequency-Domain Min-Max Optimization of Noise-Shaping Delta-Sigma Modulators,
IEEE Transactions on Signal Processing, Vol. 60, No. 6, pp. 2828-2839, 2012.

We give two matlab codes:
[ntf,R]=NTF_MINMAX(order,OSR,Hinf,f0,zf)
[ntf,R]=NTF_MINMAX_MB(order,OSR,Hinf,f,zf)
By these codes, one can obtain lowpass/bandpass (by NTF_MINMAX) and multi-band (by NTF_MINMAX_MB) filters for noise-shaping delta-sigma modulators that minimize the maximum magnitude of the noise transfer function (NTF)
in fixed frequency band(s).
