How do to fix this invalid data type error?

Hi,

I have an issue with this data type error and not quite sure what the problem is. The reset of the code is designed for a filter, and had it exported.

Invalid data type. First and second arguments must be numeric or logical.

Error in conv (line 43)
c = conv2(a(:),b(:),shape);

Error in FDM_17ES04 (line 88)
DSBSC_BPF1=conv(BPF1,Xfdm);

Either a, b, BPF1, or Xfdm is not a numeric or logical data type. You can verify this by using isnumeric and islogical.

BPF1 is set as an object filter (BPF) from filterDesigner, so you think that might be the problem?

note xfdm is defined as varaible with

I found the issue, the filter is assigned as an object rather than array. Thanks for the tip

Yes. conv requires the first two inputs to be either numeric or logical types.
