How to merge matrix and array of different size in MATLAB? -

-

i have 1 matrix of size 12 , array of size 4 given below: 

a=[23,45,1;4,6,7;9,5,0;145,65,32];                  b=[3,2,4,6];

i want new array c 

c=[23,45,1,4,6,7,9,5,0,145,65,32,3,2,4,6];

i did following : 

a=[23,45,1;4,6,7;9,5,0;145,65,32];                  b=[3,2,4,6];  a=reshape(a',12,1);             b=b(:);        c=[a b];

but giving error : 

error using ==> horzcat       cat arguments dimensions not consistent.             

a = a(:);             b = b(:);        c = [a; b];

note difference between [a b] or [a, b] , [a; b].
