resample gives me this error randomly (for the same variable)
x is 166500 X 60 matrix y= resample (x,1,5) gives me inconsistently the following error:
Error using .* Matrix dimensions must agree.
Error in resample (line 75) h = p*firls( L-1, [0 2*fc 2*fc 1], [1 1 0 0]).*kaiser(L,bta)' ;
any suggestions ?
Thanks,
R

Hi R, Can you please tell us which version of MATLAB you are using. resample() is strictly mean to work on a sequence (a 1D vector), but it should resample the columns, so it should work with your matrix.
Can you confirm that you do not have a non-MathWorks' version of firls.m installed that precedes the Signal Processing Toolbox version on your path?
If you enter:
>>which firls
what is returned?
And please do give your MATLAB version.

The kaiser function also seems like a possibility and since p comes from the rat function, you should also check that.
