Try built-in functions.

[Walter Roberson]

No, built-in functions are functions implemented in non-MATLAB code. Some of the functions mentioned above, such as linspace, have been implemented in MATLAB. You can

type linspace

to see its source.

A more accurate term would be "library functions".

"butter" and "filtfilt" are part of the Signal Processing Toolbox. They would probably be referred to as "toolbox functions", but "library functions" would also be correct.

I vote for Walter's suggestion "toolbox functions".
