Help required for rcosine function

[Abbas Haider]

I am supposed to design a raised cosine pulse shaping filter. as per the given instructions at Mathworks when i try to compile the code (even the given examples) i get the following error.
____________ERROR_____________
>> num = rcosine(1,8,'sqrt'); % Transfer function of filter
??? Undefined command/function 'firrcos'.

Error in ==> rcosfir at 89
b=firrcos(rate*(N_T(2)-N_T(1)),1/(2*T),r,rate/T,'r','sqrt',-N_T(1)*rate)*sqrt(rate);

Error in ==> rcosine at 87
num = rcosfir(R, Delay, FsDFd, 1/Fd, filt_type);
________________________________
Can somebody pls help me?

Thanks,

Did you read the error message?
It says quite clearly that it cannot find the function firrcos

Do you have the Signal Processing Toolbox?

I am not sure, if i have Signal processing toolbox.. how to check if i have it or not with my matlab package?

--
but firrcos and rcosfir are the functions that are built in.. and they are called from within rcosine..

>> which firrcos
<snip>\toolbox\signal\signal\firrcos.m

And if you type in "ver", the listing will show which toolboxes you are licensed for. If it doesn't include "Signal Processing Toolbox", you're SOL.
