app designer says cosd "undefined function"

cosd not working in app designer. it works fine in matlab just not in the app designer. app designer says "undefined funtion"

[Sean de Wolski]

Can you show the full error message?

[John D'Errico]

I wonder if it might have been something along these lines:

cosd(uint8(1))
Undefined function 'cosd' for input arguments of type 'uint8'.

[Isaac O'Neal]

Undefined function 'cosd' for input arguments of type 'matlab.ui.control.NumericEditField'.

[Geoff Hayes]

Isaac - please show us how you are using/calling cosd. It sounds like you are passing in a control rather than a (numeric) angle.

[Isaac O'Neal]

Answer 1

[Geoff Hayes]

Isaac - you are obtaing the angle as

angle = app.Angle;

where presumably Angle is the handle to the matlab.ui.control.NumericEditField and so is not the angle itself. You may need to do someting more like

angle = app.Angle.Value;

to get the value of the angle. (I'm assuming that since this is a NumericEditField, you don't have to convert the above from a string to a number.)

Note that if the above works, you will need to do the same for the initial population and initial velocity.
