Asked by Anand

I wrote a simple function to swap variables. I am using MATLAB in Win 7.

function [x,y]= swap(u,v) x=v; y=u;

I get a make error stating

"Making simulation target "ex2_sfun", ...

C:\Users\....(some location)>"c:\users\(some location)" -f ex2_sfun.lmk The system cannot find the path specified."

I get Parse Ok and Code Ok.

What might be the problem? Please help me.

Probably there is a simulink model with the same name. Try to use a slightly different function name for youe swap function such as swap01 or swapThem..etc. Also check your path and set it to current Matlab directory. Regards.

Hi, I am a newbie. How to set path to current Matlab directory ?

"pwd" command gives me C:/Documents/Matlab" . Is it my Matlab directory ? Where shud I set this path ?

Regards

From Matlab menu (File), then goto (Set Path) and click on (Add Folder) to add a single directory or (Add with subfolders) to add a folder and its children. You can also type

pathtool

to reach the same interface.

Don't forget to click (save) after you finish setting your path :)

Could you run the command

getenv PATHin MATLAB and see if one of the following is true:## Anand

There is no "&" or "C:/Windows/System32/..." in the path variable.. There are lots of paths separated by semicolons (;)..

Okay, the pronlem could be that you are missing System32 on your PATH variable. Could you make sure that "C:/Windows/System32/" exists on your machine and add that to the System PATH environment variable? Then restart MATLAB and try your model again.

Hi.. By System PATH u mean the Path variable in Environmental variables of computer properties? I added in that and still it not working. Again it is giving me Make Error.

Now, when you run "getenv PATH" from MATLAB, does "C:/Windows/System32/" show up in the list?
