pcode does not run in matlab command line mode

Hi there,

I have an issue about p file generated by the pcode. We have source control rules so I need to compile the source code to pcode. Here is the funny thing.

if I run

-------------------------------------------
/apps/matlab/bin/matlab  < runModel.m
-------------------------------------------

it works. If I run

-------------------------------------------
/apps/matlab/bin/matlab  < runModel.p
-------------------------------------------

It gives me an error

-------------------------------------------
>> ??? v00.00v00.00
       |
Error: Unexpected MATLAB expression.

>> >> ??? ÀµZßµ
    |
Error: The input character is not valid in MATLAB statements or expressions.
-------------------------------------------

Here it gets funnier, If i run matlab first then run p file

-------------------------------------------
>> bash-3.2$ /apps/matlab/bin/matlab

/apps/matlab/bin/matlab -r "try runModel; catch ME; end; quit"

The "<" operator in Unix is redirecting from an input file, almost as if what was in the input file was typed in response to command prompts. That can work for source code in text form, that that cannot work for .p files as those are not in source code format.

thanks for that explanation. that is awesome. so simple, and so clear.

so what can i do if i want to run a p file from command line? do I have to compile it to a standalone binary file?

The shown code works for a P-file already, so I do not understand your question in this comment.

Just give the name without the extension. .p files have priority over .m files with the same name.
