Sir I also created one but not a function like yours...preferred script file instead..but functions are still better to handle...so thanks Sir..:)

@min min: It is a function not a code, it will not work till you pass P and k to it in command window

@Tamir: It depends on what name you have used to save this file, will be called by that name only,
I have used this code to even encrypt 100 pages of text file, it is working fine
this is the result for what you asked
P='Hello World and Welcome to Matlab cryptogrpahy'
k=3
C=caesar_E(P,k)
C=Khoor Zruog dqg Zhofrph wr Pdwode fubswrjusdkb

What I did notice is when you extend it above 3 words it doesnt do the shift so its missing that part
try to run this code and you will understand what I meant :

P='Hello World and Welcome to Matlab cryptogrpahy'
k=3
C=caesar_E(P,k)
CD=caesar_D(C,k)

It should work if you use the caesar_E instead of caeasar I think the help files didnt express well how to use the function but its good try
