xcorr does not require Signal Processing Toobox in Matlab R2019a and later.
For Matlab releases prior to 19a,, you'll need the Signal Processing Toobox as the error message indicates. Alternatively, you could compute the cross correlation with your own function or search for an alternative on the File Exchange.
