Cannot find builtin function 'waitbar'

Hi,

I am calling builtin fucntion to run waitbar in R2017b but got an error:

Cannot find builtin function 'waitbar'.

Is waitbar function not supported by builtin?

Thanks.

Can you show the output of

which waitbar -all

The document says that built-in function is not written in m language but only a description in m file. So the waitbar seems not to be a built-in fucntion.

How are you calling waitbar in your code?

[Steven Lord]

The builtin function is intended to call built-in functions, not functions implemented by MathWorks as function files with the .m or .mlx extensions. The waitbar function is implemented as a .m file. Compare with:

builtin('sin', pi) % sin is a built-in function, its sin.m is help text only

ans = 1.2246e-16

builtin('why') % why is implemented in the file why.m

Cannot find builtin function 'why'
