Undefined function 'resample' for input arguments of type 'double'.

I keep getting the error "Undefined function 'resample' for input arguments of type 'double'."

The code i am using is a preinstalled MATLAB code, still this error keeps popping up.

what is the solution for this. can someone help as soon as possible. my data analysis is stuck because of this error

There are several resample functions. Be sure that you are using the Signal Processing Toolbox resample function. (It is necessary to have the Signal Processing Toolbox licensed and installed.)

One way to troubleshoot this is to run:

which resample -all

from your Command Window or a script.

My results for that:

C:\Program Files\MATLAB\R2020b\toolbox\signal\signal\resample.m
C:\Program Files\MATLAB\R2020b\toolbox\ident\ident\@iddata\resample.m              % Shadowed iddata method
C:\Program Files\MATLAB\R2020b\toolbox\matlab\timeseries\@timeseries\resample.m    % Shadowed timeseries method
C:\Program Files\MATLAB\R2020b\toolbox\matlab\timeseries\@tscollection\resample.m  % Shadowed tscollection method

.

I tried this as per you said, but then

toolbox\matlab\timeseries\@tscollection\resample.m

this pops up, when i add this to path and run the code again

I get the message

"the resample function can only be used for a single timeseries object"

can you explain what that means? how i can get the code to run?

[Star Strider]

The resample function only takes double arguments, although they can be vectors or matrices. You would likely have to extract the timeseries object to a double vector (or matrix), or loop through the individual rows (or columns) of your timeseries object. The loop is likely the best option.

I have no idea what your data are, so I cannot determine what the problem is. I have never used resample on timeseries objects.
