FIR II Decimation Frequency Response

Hi,

Thanks for your help. Sorry for the inconvenience. I still get into the following error:

Error using .*

Matrix dimensions must agree.

Error in fir_inspect (line 5)

sinevector=(2^(inBits-1)-1)*sin(2*pi*clock.*freqsMhz'/smpRateMhz);

It seems like the clock dimension mismatches with freqsMhz. Also, I have tested manually change the clock to 1x65, it will prompt another error on " '/ " operator. I changed to " ./ " the file can run but the simulation output is a waveform like plot which I believe due to incorrect changes from my side.

Note that I have not run the Modelsim but just testing on the .m file since there is a decim_fir_output.txt available in your folder.

Please let me know if there is any concern. Thank you.
