Undefined function 'normalize' for input arguments of type 'double'

I want to use the MATLAB function "normalize" which normalizes the data to zero mean and unit variance. During the compilation, I still get the error:

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

Although this function support double inputs.

When I typed: 

which normalize -all

I got:

C:\Program Files\MATLAB\R2017a\toolbox\signal\signal\@dfilt\normalize.m  % dfilt method

Could any one help me please?

You're likely using a version of MATLAB older than R2018a, which is when the function normalize was first introduced. The which command is showing you a normalize method for dfilt class objects (from the Signal Processing Toolbox) that existed prior, which only accepts arguments of type dfilt.
