Parks-McClellan algorithm for filter design

Dear all, i'm kinda new in Matlab and i need help, how to get Matlab code to design filter in Matlab with Parks-McClellan algorithm for this parameters:

0 ≤ H(e^jω) ≤ 0.01 0≤ω≤0.2π

0.95 ≤ H(e^jω) ≤ 1.05 0.35≤ω≤0.65π

0≤ H(e^jω) ≤0.03 0.75≤ω≤π

can someone show me the code or hint how to get filters in Matlab.

Thanks in advance

If you have the Signal Processing Toolbox, you can use firpm.m Or you can use fdesign.bandpass with a specification string that supports 'equiripple'
