回复： Calling functions / subroutines

[Duc Ha]

Hi,

Can Mathscript handle functions subroutines?  In the Mathscript window I get the error message

"unexpected token: function"

For example:

function y = xx(a, b, c)

   ...

   ....

return

where xx is being called from the main program.

Thanks in advance

Hi,

If you want to invoke a subroutine, the best way is to save the function as a .m script. The name of the script should be the same as your function name. Save the script in the MathScript searching path. You can set the searching path in MathScript properties. Just use Ctrl+I in MathScript Window. Then, you can invoke your subroutine in MathScript Window, such as xx(a, b, c).

Hi,

Thats for the response.  It appears to be calling up the functions. 

Can I evoke m files using the Mathscript Node environment?  If so what command do I use to specify the search path?

Thanks in advance

Hi,

Yes, you can invoke user-defined function in either MathScript Window or MathScript Node. You can use path or addpath to specify the search path list. Another way to specify the search path list is in LabVIEW Options. Find it at Tools->Options ...->MathScript: Search Paths.

Hello,

Of the two options that ttrr presents for setting the search path, the Tools->Options dialog is much preferred. If you use this method, performance of your scripts will be much faster. Use the path and addpath functions only when you want to change the search path programatically at run-time.
