Undefined function or variable

Hi

I am working on a simulation project, some output of the simulation will be as input for matlab functions,

inside the Matlab function there are variables which are defined in a mfile , but the problem every time I run the simulation I got the message "Undefined function or variable " which are defined in m.file

anyone know how this can be solve?

The question should be do the variables exist in the workspace at the time you want to use them? Having them defined in a separate file does not help. You need to run that script inside the function if you want the variables it defines to be available. Of course, that will only work if your m-file itself is a script and not a function.

so, How I can run the scripte inside the function ?

[Cris LaPierre]

Scripts can be run by calling them by name, similar to a function. They just don't have any inputs. So if I had a script called vardef that defined my variables a and b, I could do this

...
vardef
x = b*sin(a);
