MATLAB: Too many input arguments?

[Ahmed Alaa]

I am using the built in MATLAB function buffer() but received the error message
-> Too Many Input arguments???
Although the number of inputs are correct.

I checked whether I have other m-files named buffer, but I didn't find one. The strange point is that it works on the PC at office, but doesn't work on my laptop although I use the same MATLAB version in both.

What is the problem then?

1 - May be the version of Matlab diffres
2- Save as the program and see if the problem fixes
3 - check the function in the Help of your Matlab program at home

post here the exact script which gives the error, we'll point out the mistake

 

[Ahmed Alaa]

In my code I use buffer for dividing a data file into payload packets, I used it before om my SAME laptop for speaker recognition project and it was working properly. Now I only try to call buffer from the comand prompt:

>> buffer([1 0 1 1 0 1], 2)

The out put should be the matrix:
[ 1 1 0 ; 0 1 1];

But I receive the error message stated before.

 

[Communications_Engineer]

has there been a Matlab version change now?

by the way it can be done as,

x = [1 0 1 1 0 1];
y = reshape(x,2,[])

Added after 1 minutes:

for any x such that length(x)/2 is integer


some manipulation can make the above mentioned 'condition/limitation' go away as well

That is probably because the MATLAB version issue, ur commands works fine on my machine.

The alternative method from communications_engineer is also good

 

[Ahmed Alaa]

No, It was working fine on my machine too. I think there is a problem like having an m-file named 'buffer' or so that causes this conflict.

 

[Communications_Engineer]

if your file name is similar to a built-in matlab function, the matlab function will not work, if it works, the results will not be correct.

Added after 26 seconds:

you have identified it correctly

There are many functions in the Matlab and if we used the same name in my functions it'd cause the above problem... I also was on the above way and get this message.. I therefore use Hungarian words to name my functions.. )) T

 

[Ahmed Alaa]

yes Tamas but I don't have a function called buffer.
I'll try using Hungarian words
