I want to design the filter in the figure with desingfilt command.

My code for to obtain it is;

d2 = designfilt('arbmagfir', ...

'FilterOrder',205, ...

'NumBands',2, ...

'BandFrequencies1',[90 110], ...

'BandFrequencies2',[490 510], ...

'BandAmplitudes1',[2 2], ...

'BandAmplitudes2',[0 0], ...

'DesignMethod','ls', ...

'BandWeights1',[1 1]/10, ...

'BandWeights2',[3 1], ...

'SampleRate',5000) ;

But I'm getting errors. What am I doing wrong?

As is you command codes are running ok in MATLAB 2020b.
