i have a vector
V1 = [ 45 -45 45 -45 45 -45 45 -45 45 -45 45 -45 45 -45 45 -45 45 -45];
V2 = [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0];
i want to enter just for 1 time 0 and multiple of 20 and automatically expand. for 45 and -45, just want to enter 45 and -45 and multiple of 9. and new vector v make automatically [V1, V2]; or suggest any program to automatically MATLAB ask to enter any value like 0 or 45 or -45... and how many times, and value how many times want to enter each value? and automatically create new vector
V = [V1, V2....Vn] or V = [V(1), V(2)...V(n)];

function V = formvec
a = input('Enter the array to repeat:') ;
N = input('Number of times to repeat:') ;
V = repmat(a,[1 N]);

Tell me one thing more
syms formvec
value = [repmat([formvec], [1,11])] %number of required repeatation 1,2...
Convert formvec to variable. which directly run.

K1 = [45 -45] ;
v1 = repmat(K1,[1 9]) ;
K2 = 0 ;
V2 = repmat(K2,[1 20]) ;
V3 = zeros(1,20) ;
doc repmat, zeros,ones etc.

Can you tell me program to generate it automatically?
N = input(' No of value to repeat');
generate repmat according to N and automatically ask value and number of value to be combine in v.
v = [repmat([K1],[1 input1]),repmat([K2],[1 input2]),repmat([K3],[1 input3])]
