Check for missing argument or incorrect argument data type in call to function 'resample'

Im trying to code a simple downsample program and I keep getting this error, and Idk why

My code:

Matrix= readmatrix('DSTXTBU.xlsx');

x=Matrix(:,1);
y=Matrix(:,2);
figure(1)
plot(x,y);


%Downsampling 1
DS1x=x;
XDS1=resample(x,1,80);

DS1y=x;
YDS1=resample(DS1y,1,80);
figure(2)
plot(XDS1,YDS1)

Are there any NaN in the vectors x and y? If so delete them and try again.

What is class(x)

readmatrix can return non-numeric matrices. You might need to use Headerlines when you read

I realized the problem is that I don't have the toolbox installed to use the function, thanks everyone for the help

Hi, I have the same problem..

what toolbox did you install?

[Walter Roberson]

Signal Processing Toolbox is needed for resample()

Make sure to install the Signal Processing Toolbox to use the 'resampling' function.

Add it as an addon toolbox from MATLAB itself!
