as we know that vect2mat is in built function. I'm confused and worried about this error. Please help me with this!!
function [c]=enc(m,n,mpk)
m1=double(m);
size=numel(m1);
c1=m1;
for i=1:size
m2=m1(i)^mpk;
c1(i)=mod(m2,n);
end
count=6-rem(size,6);
if rem(size,6)==0
c2=vect2mat(c1,6);
else
count1=zeros(1,count);
c11=[c1,count1];
c2=vect2mat(c11,6);
end
n1=[mpk,n,0,0,0,0];
c=[n1;c2];

you mean vec2mat?
Note that you'd need communication systems toolbox for that.
But otherwise you could use reshape!

Another thing, do not override the inbuilt functions! in your code, you're creating a variable called size, I'd suggest you to rename it.
